Definitions
- the present invention relates to a polycyclic aromatic compound, an organic electroluminescent element using the same, an organic field effect transistor and an organic thin film solar cell, and a display device and a lighting device.
- the “organic electroluminescent device” may be referred to as “organic EL device” or simply “device”.
- a display device using an electroluminescent element can be variously researched because it can save power and can be made thin. Furthermore, an organic electroluminescent element made of an organic material can be easily reduced in weight and size. Therefore, it has been actively studied. In particular, the development of organic materials that have emission characteristics such as blue, which is one of the three primary colors of light, and the development of organic materials that have the ability to transport charges such as holes and electrons (possibly becoming a semiconductor or superconductor). Development has been actively researched so far, regardless of whether it is a high molecular compound or a low molecular compound.
- the organic EL element has a structure including a pair of electrodes composed of an anode and a cathode and one or a plurality of layers arranged between the pair of electrodes and containing an organic compound.
- Layers containing an organic compound include a light emitting layer and a charge transport / injection layer that transports or injects charges such as holes and electrons, and various organic materials suitable for these layers have been developed.

- polycyclic aromatic compounds having an extended ⁇ conjugated system generally, but the redox stability is excellent, because HOMO-LUMO gap and triplet excitation energy (band gap Eg of the thin film) (E T) is low, It has been considered unsuitable as a host material.
- Patent Document 6 reports a polycyclic aromatic compound containing boron and an organic EL device using the same.
- layer materials especially dopant materials.

本発明に係る多環芳香族化合物は、有機デバイス用材料として用いることができる。有機デバイスとしては、例えば、有機電界発光素子、有機電界効果トランジスタまたは有機薄膜太陽電池などがあげられる。
以下に、本実施形態に係る有機EL素子について図面に基づいて詳細に説明する。図1は、本実施形態に係る有機EL素子を示す概略断面図である。
図1に示された有機EL素子100は、基板101と、基板101上に設けられた陽極102と、陽極102の上に設けられた正孔注入層103と、正孔注入層103の上に設けられた正孔輸送層104と、正孔輸送層104の上に設けられた発光層105と、発光層105の上に設けられた電子輸送層106と、電子輸送層106の上に設けられた電子注入層107と、電子注入層107の上に設けられた陰極108とを有する。
基板101は、有機EL素子100の支持体であり、通常、石英、ガラス、金属、プラスチックなどが用いられる。基板101は、目的に応じて板状、フィルム状、またはシート状に形成され、例えば、ガラス板、金属板、金属箔、プラスチックフィルム、プラスチックシートなどが用いられる。なかでも、ガラス板、および、ポリエステル、ポリメタクリレート、ポリカーボネート、ポリスルホンなどの透明な合成樹脂製の板が好ましい。ガラス基板であれば、ソーダライムガラスや無アルカリガラスなどが用いられ、また、厚みも機械的強度を保つのに十分な厚みがあればよいので、例えば、0.2mm以上あればよい。厚さの上限値としては、例えば、2mm以下、好ましくは1mm以下である。ガラスの材質については、ガラスからの溶出イオンが少ない方がよいので無アルカリガラスの方が好ましいが、SiO2などのバリアコートを施したソーダライムガラスも市販されているのでこれを使用することができる。また、基板101には、ガスバリア性を高めるために、少なくとも片面に緻密なシリコン酸化膜などのガスバリア膜を設けてもよく、特にガスバリア性が低い合成樹脂製の板、フィルムまたはシートを基板101として用いる場合にはガスバリア膜を設けるのが好ましい。
陽極102は、発光層105へ正孔を注入する役割を果たす。なお、陽極102と発光層105との間に正孔注入層103および/または正孔輸送層104が設けられている場合には、これらを介して発光層105へ正孔を注入することになる。
正孔注入層103は、陽極102から移動してくる正孔を、効率よく発光層105内または正孔輸送層104内に注入する役割を果たす。正孔輸送層104は、陽極102から注入された正孔または陽極102から正孔注入層103を介して注入された正孔を、効率よく発光層105に輸送する役割を果たす。正孔注入層103および正孔輸送層104は、それぞれ、正孔注入・輸送材料の一種または二種以上を積層、混合するか、正孔注入・輸送材料と高分子結着剤の混合物により形成される。また、正孔注入・輸送材料に塩化鉄(III)のような無機塩を添加して層を形成してもよい。
このような高分子化合物および高分子架橋体の用途の詳細については後述する。
発光層105は、電界を与えられた電極間において、陽極102から注入された正孔と、陰極108から注入された電子とを再結合させることにより発光する層である。発光層105を形成する材料としては、正孔と電子との再結合によって励起されて発光する化合物(発光性化合物)であればよく、安定な薄膜形状を形成することができ、かつ、固体状態で強い発光(蛍光)効率を示す化合物であるのが好ましい。本発明では、発光層用の材料として、ホスト材料と、例えばドーパント材料としての上記一般式(1)で表される多環芳香族化合物とを用いることができる。

このような高分子化合物および高分子架橋体の用途の詳細については後述する。
陰極108は、電子注入層107および電子輸送層106を介して、発光層105に電子を注入する役割を果たす。
以上の正孔注入層、正孔輸送層、発光層、電子輸送層および電子注入層に用いられる材料は単独で各層を形成することができるが、高分子結着剤としてポリ塩化ビニル、ポリカーボネート、ポリスチレン、ポリ(N-ビニルカルバゾール)、ポリメチルメタクリレート、ポリブチルメタクリレート、ポリエステル、ポリスルホン、ポリフェニレンオキサイド、ポリブタジエン、炭化水素樹脂、ケトン樹脂、フェノキシ樹脂、ポリアミド、エチルセルロース、酢酸ビニル樹脂、ABS樹脂、ポリウレタン樹脂などの溶剤可溶性樹脂や、フェノール樹脂、キシレン樹脂、石油樹脂、ユリア樹脂、メラミン樹脂、不飽和ポリエステル樹脂、アルキド樹脂、エポキシ樹脂、シリコーン樹脂などの硬化性樹脂などに分散させて用いることも可能である。
有機EL素子を構成する各層は、各層を構成すべき材料を蒸着法、抵抗加熱蒸着、電子ビーム蒸着、スパッタリング、分子積層法、印刷法、スピンコート法またはキャスト法、コーティング法などの方法で薄膜とすることにより、形成することができる。このようにして形成された各層の膜厚については特に限定はなく、材料の性質に応じて適宜設定することができるが、通常2nm~5000nmの範囲である。膜厚は通常、水晶発振式膜厚測定装置などで測定できる。蒸着法を用いて薄膜化する場合、その蒸着条件は、材料の種類、膜の目的とする結晶構造および会合構造などにより異なる。蒸着条件は一般的に、ボート加熱温度+50~+400℃、真空度10-6~10-3Pa、蒸着速度0.01~50nm/秒、基板温度-150~+300℃、膜厚2nm~5μmの範囲で適宜設定することが好ましい。
適当な基板上に、陽極材料の薄膜を蒸着法などにより形成させて陽極を作製した後、この陽極上に正孔注入層および正孔輸送層の薄膜を形成させる。この上にホスト材料とドーパント材料を共蒸着し薄膜を形成させて発光層とし、この発光層の上に電子輸送層、電子注入層を形成させ、さらに陰極用物質からなる薄膜を蒸着法などにより形成させて陰極とすることにより、目的の有機EL素子が得られる。なお、上述の有機EL素子の作製においては、作製順序を逆にして、陰極、電子注入層、電子輸送層、発光層、正孔輸送層、正孔注入層、陽極の順に作製することも可能である。
湿式成膜法は、有機EL素子の各有機層を形成し得る低分子化合物を液状の有機層形成用組成物として準備し、これを用いることによって実施される。この低分子化合物を溶解する適当な有機溶媒がない場合には、当該低分子化合物に反応性置換基を置換させた反応性化合物として溶解性機能を有する他のモノマーや主鎖型高分子と共に高分子化させた高分子化合物などから有機層形成用組成物を準備してもよい。
(手順1)陽極の真空蒸着法による成膜
(手順2)正孔注入層用材料を含む正孔注入層形成用組成物の湿式成膜法による成膜
(手順3)正孔輸送層用材料を含む正孔輸送層形成用組成物の湿式成膜法による成膜
(手順4)ホスト材料とドーパント材料を含む発光層形成用組成物の湿式成膜法による成膜
(手順5)電子輸送層の真空蒸着法による成膜
(手順6)電子注入層の真空蒸着法による成膜
(手順7)陰極の真空蒸着法による成膜
この手順を経ることで、陽極/正孔注入層/正孔輸送層/ホスト材料とドーパント材料からなる発光層/電子輸送層/電子注入層/陰極からなる有機EL素子が得られる。
もちろん、下層の発光層の溶解を防ぐ手段があったり、また上記手順とは逆に陰極側から成膜する手段などを用いることで、電子輸送層用材料や電子注入層用材料を含む層形成用組成物として準備して、それらを湿式成膜法により成膜できる。
有機層形成用組成物の成膜化には、レーザー加熱描画法(LITI)を用いることができる。LITIとは基材に付着させた化合物をレーザーで加熱蒸着する方法で、基材へ塗布される材料に有機層形成用組成物を用いることができる。
成膜の各工程の前後に、適切な処理工程、洗浄工程および乾燥工程を適宜入れてもよい。処理工程としては、例えば、露光処理、プラズマ表面処理、超音波処理、オゾン処理、適切な溶媒を用いた洗浄処理および加熱処理等が挙げられる。さらには、バンクを作製する一連の工程も挙げられる。
有機層形成用組成物は、有機EL素子の各有機層を形成し得る低分子化合物、または当該低分子化合物を高分子化させた高分子化合物を有機溶媒に溶解させて得られる。例えば、発光層形成用組成物は、第1成分として少なくとも1種のドーパント材料である多環芳香族化合物(またはその高分子化合物)と、第2成分として少なくとも1種のホスト材料と、第3成分として少なくとも1種の有機溶媒とを含有する。第1成分は、該組成物から得られる発光層のドーパント成分として機能し、第2成分は発光層のホスト成分として機能する。第3成分は、組成物中の第1成分と第2成分を溶解する溶媒として機能し、塗布時には第3成分自身の制御された蒸発速度により平滑で均一な表面形状を与える。
有機層形成用組成物は少なくとも一種の有機溶媒を含む。成膜時に有機溶媒の蒸発速度を制御することで、成膜性および塗膜の欠陥の有無、表面粗さ、平滑性を制御および改善することができる。また、インクジェット法を用いた成膜時は、インクジェットヘッドのピンホールでのメニスカス安定性を制御し、吐出性を制御・改善することができる。加えて、膜の乾燥速度および誘導体分子の配向を制御することで、該有機層形成用組成物より得られる有機層を有する有機EL素子の電気特性、発光特性、効率、および寿命を改善することができる。
少なくとも1種の有機溶媒の沸点は、130℃~300℃であり、140℃~270℃がより好ましく、150℃~250℃がさらに好ましい。沸点が130℃より高い場合、インクジェットの吐出性の観点から好ましい。また、沸点が300℃より低い場合、塗膜の欠陥、表面粗さ、残留溶媒および平滑性の観点から好ましい。有機溶媒は、良好なインクジェットの吐出性、成膜性、平滑性および低い残留溶媒の観点から、2種以上の有機溶媒を含む構成がより好ましい。一方で、場合によっては、運搬性などを考慮し、有機層形成用組成物中から溶媒を除去することで固形状態とした組成物であってもよい。
高沸点の貧溶媒を加えることで成膜時に低沸点の良溶媒が先に揮発し、組成物中の含有物の濃度と貧溶媒の濃度が増加し速やかな成膜が促される。これにより、欠陥が少なく、表面粗さが小さい、平滑性の高い塗膜が得られる。
有機層形成用組成物に用いられる有機溶媒としては、アルキルベンゼン系溶媒、フェニルエーテル系溶媒、アルキルエーテル系溶媒、環状ケトン系溶媒、脂肪族ケトン系溶媒、単環性ケトン系溶媒、ジエステル骨格を有する溶媒および含フッ素系溶媒などがあげられ、具体例として、ペンタノール、ヘキサノール、ヘプタノール、オクタノール、ノナノール、デカノール、ウンデカノール、ドデカノール、テトラデカノール、ヘキサン-2-オール、ヘプタン-2-オール、オクタン-2-オール、デカン-2-オール、ドデカン-2-オール、シクロヘキサノール、α-テルピネオール、β-テルピネオール、γ-テルピネオール、δ-テルピネオール、テルピネオール(混合物)、エチレングリコールモノメチルエーテルアセテート、プロピレングリコールモノメチルエーテルアセテート、ジエチレングリコールジメチルエーテル、ジプロピレングリコールジメチルエーテル、ジエチレングリコールエチルメチルエーテル、ジエチレングリコールイソプロピルメチルエーテル、ジプロピレングリコールモノメチルエーテル、ジエチレングリコールジエチルエーテル、ジエチレングリコールモノメチルエーテル、ジエチレングリコールブチルメチルエーテル、トリプロピレングリコールジメチルエーテル、トリエチレングリコールジメチルエーテル、ジエチレングリコールモノブチルエーテル、エチレングリコールモノフェニルエーテル、トリエチレングリコールモノメチルエーテル、ジエチレングリコールジブチルエーテル、トリエチレングリコールブチルメチルエーテル、ポリエチレングリコールジメチルエーテル、テトラエチレングリコールジメチルエーテル、p-キシレン、m-キシレン、o-キシレン、2,6-ルチジン、2-フルオロ-m-キシレン、3-フルオロ-o-キシレン、2-クロロベンゾ三フッ化物、クメン、トルエン、2-クロロ-6-フルオロトルエン、2-フルオロアニソール、アニソール、2,3-ジメチルピラジン、ブロモベンゼン、4-フルオロアニソール、3-フルオロアニソール、3-トリフルオロメチルアニソール、メシチレン、1,2,4-トリメチルベンゼン、t-ブチルベンゼン、2-メチルアニソール、フェネトール、ベンゾジオキソール、4-メチルアニソール、s-ブチルベンゼン、3-メチルアニソール、4-フルオロ-3-メチルアニソール、シメン、1,2,3-トリメチルベンゼン、1,2-ジクロロベンゼン、2-フルオロベンゾニトリル、4-フルオロベラトロール、2,6-ジメチルアニソール、n-ブチルベンゼン、3-フルオロベンゾニトリル、デカリン(デカヒドロナフタレン)、ネオペンチルベンゼン、2,5-ジメチルアニソール、2,4-ジメチルアニソール、ベンゾニトリル、3,5-ジメチルアニソール、ジフェニルエーテル、1-フルオロ-3,5-ジメトキシベンゼン、安息香酸メチル、イソペンチルベンゼン、3,4-ジメチルアニソール、o-トルニトリル、n-アミルベンゼン、ベラトロール、1,2,3,4-テトラヒドロナフタレン、安息香酸エチル、n-ヘキシルベンゼン、安息香酸プロピル、シクロヘキシルベンゼン、1-メチルナフタレン、安息香酸ブチル、2-メチルビフェニル、3-フェノキシトルエン、2,2’-ビトリル、ドデシルベンゼン、ジペンチルベンゼン、テトラメチルベンゼン、トリメトキシベンゼン、トリメトキシトルエン、2,3-ジヒドロベンゾフラン、1-メチル-4-(プロポキシメチル)ベンゼン、1-メチル-4-(ブチルオキシメチル)ベンゼン、1-メチル-4-(ペンチルオキシメチル)ベンゼン、1-メチル-4-(ヘキシルオキシメチル)ベンゼン、1-メチル-4-(ヘプチルオキシメチル)ベンゼンベンジルブチルエーテル、ベンジルペンチルエーテル、ベンジルヘキシルエーテル、ベンジルヘプチルエーテル、ベンジルオクチルエーテルなどが挙げられるが、それだけに限定されない。また、溶媒は単一で用いてもよく、混合してもよい。
有機層形成用組成物は、その性質を損なわない範囲で、任意成分を含んでいてもよい。任意成分としては、バインダーおよび界面活性剤等が挙げられる。
有機層形成用組成物は、バインダーを含有していてもよい。バインダーは、成膜時には膜を形成するとともに、得られた膜を基板と接合する。また、該有機層形成用組成物中で他の成分を溶解および分散および結着させる役割を果たす。
有機層形成用組成物は、例えば、有機層形成用組成物の膜面均一性、膜表面の親溶媒性および撥液性の制御のために界面活性剤を含有してもよい。界面活性剤は、親水性基の構造からイオン性および非イオン性に分類され、さらに、疎水性基の構造からアルキル系およびシリコン系およびフッ素系に分類される。また、分子の構造から、分子量が比較的小さく単純な構造を有する単分子系および分子量が大きく側鎖や枝分かれを有する高分子系に分類される。また、組成から、単一系、二種以上の界面活性剤および基材を混合した混合系に分類される。該有機層形成用組成物に用いることのできる界面活性剤としては、全ての種類の界面活性剤を用いることができる。
有機層形成用組成物における各成分の含有量は、有機層形成用組成物中の各成分の良好な溶解性、保存安定性および成膜性、ならびに、該有機層形成用組成物から得られる塗膜の良質な膜質、また、インクジェット法を用いた場合の良好な吐出性、該組成物を用いて作製された有機層を有する有機EL素子の、良好な電気特性、発光特性、効率、寿命の観点を考慮して決定される。例えば、発光層形成用組成物の場合には、第1成分が発光層形成用組成物の全重量に対して、0.0001重量%~2.0重量%、第2成分が発光層形成用組成物の全重量に対して、0.0999重量%~8.0重量%、第3成分が発光層形成用組成物の全重量に対して、90.0重量%~99.9重量%が好ましい。

波長変換機能を有する組成物は、式(1)の多環芳香族化合物のほか、バインダー樹脂、その他の添加剤、および溶媒を含んでいてもよい。バインダー樹脂としては、例えば国際公開第2016/190283号の段落[0173]~[0176]に記載の樹脂を用いることができる。その他の添加剤としては、国際公開第2016/190283号の段落[0177]~[0181]に記載の化合物を用いることができる。また、溶媒としては、これらの材料を適切に溶解し得る溶媒を用いればよい。
波長変換フィルムは波長変換機能を有する組成物を硬化させることにより形成される波長変換層を含む。組成物から波長変換層を作製する方法としては公知のフィルム形成方法を参照することができる。波長変換フィルムは式(1)の多環芳香族化合物を含む組成物から形成される波長変換層のみからなっていてもよく、他の波長変換層(例えば、青色光を緑色光や赤色光に変換する波長変換層、青色光や緑色光を赤色光に変換する波長変換層)を含んでいてもよい。さらに波長変換フィルムは基材層や、色変換層の酸素、水分や熱による劣化を防ぐためのバリア層を含んでいてもよい。

サンプルの準備
評価対象の化合物の吸収特性と発光特性(蛍光と燐光)を評価する場合、化合物を溶媒に溶解して溶媒中で評価する場合と薄膜状態で評価する場合がある。さらに、薄膜状態で評価する場合は、化合物の有機EL素子における使用の態様に応じて、化合物のみを薄膜化し評価する場合と化合物を適切なマトリックス材料中に分散して薄膜化して評価する場合がある。
吸収スペクトルの測定は、紫外可視近赤外分光光度計((株)島津製作所、UV-2600)を用いて行った。また、蛍光スペクトルまたは燐光スペクトルの測定は、分光蛍光光度計(日立ハイテク(株)製、F-7000)を用いて行った。
蛍光寿命測定装置(浜松ホトニクス(株)製、C11367-01)を用いて300Kで蛍光寿命を測定した。適切な励起波長で測定される極大発光波長において蛍光寿命の早い成分と遅い成分を観測した。蛍光を発光する一般的な有機EL材料の室温における蛍光寿命測定では、熱による3重項成分の失活により、燐光に由来する3重項成分が関与する遅い成分が観測されることはほとんどない。評価対象の化合物において遅い成分が観測された場合は、励起寿命の長い3重項エネルギーが熱活性化により1重項エネルギーに移動して遅延蛍光として観測されたことを示すことになる。
前述の方法で得られた吸収スペクトルの長波長末端A(nm)からEg=1240/Aで算出される。
一重項励起エネルギー(ES)は、蛍光スペクトルの極大発光波長B(nm)からES=1240/Bで算出される。また、三重項励起エネルギー(ET)は、燐光スペクトルの極大発光波長C(nm)からET=1240/Cで算出される。
測定の結果、吸収ピーク波長482nm、蛍光ピーク波長503nm、蛍光ピークの半値幅33nm、PLQY99%以上の、空色~緑色で半値幅の狭い発光が得られた(図2および図3)。
化合物(1-230)のトルエン溶液中における遅延蛍光寿命を計測した。5.0~40nsecまでの減衰カーブより蛍光寿命tau(prompt)を算出したところ、6.4nsecであった(図4)。また、6.0~25μsecまでの減衰カーブより遅延蛍光寿命tau(Delay)を算出したところ、7.7μsecだった(図5)。これらより、J. Am. Chem. Soc. 2014, 136, 18070-18081およびNat. Commun. 2015, 6, 8476.に記載の方法を用いて、ΔESTを0.14eVと見積もった。
測定の結果、吸収ピーク波長482nm、蛍光ピーク波長504nm、蛍光ピークの半値幅31nm、PLQY94%の、空色~緑色で半値幅の狭い発光が得られた。
化合物(1-232)のトルエン溶液中における遅延蛍光寿命を計測した。4.6~40nsecまでの減衰カーブより蛍光寿命tau(prompt)を算出したところ、5.7nsecであった。また、5.8~6.6μsecまでの減衰カーブより遅延蛍光寿命tau(Delay)を算出したところ、1.8μsecだった。これらより、J. Am. Chem. Soc. 2014, 136, 18070-18081およびNat. Commun. 2015, 6, 8476.に記載の方法を用いて、ΔESTを0.11eVと見積もった。
測定の結果、吸収ピーク波長439nm、蛍光ピーク波長456nm、燐光ピーク波長492nm、蛍光ピークの半値幅36nm、PLQY86%の、深い青色かつ半値幅の狭い発光が得られた(図6)。また蛍光ピーク波長および燐光ピーク波長よりΔESTは0.20eVと算出した。
比較化合物1を1重量%の濃度でPMMAに分散して作製した薄膜から遅延蛍光寿命を計測した。100~250μsecまでの減衰カーブより遅延蛍光寿命tau(Delay)を算出したところ、94μsecであった(図7)。
以上のように、本発明の化合物は、十分に良好なPLQYおよび非常に小さなtau(delay)を有し、半値幅が狭く深い青色で発光するため、TADF機構を利用する有機EL素子のドーパントとして好適である。
評価項目としては、駆動電圧(V)、発光波長(nm)、CIE色度(x,y)、外部量子効率(%)、発光スペクトルの最大波長(nm)、半値幅(nm)およびロールオフなどがある。これらの評価項目は、適切な発光輝度時の値を用いることができる。
有機EL素子を作製し、電圧を印加して電流密度、輝度、色度および外部量子効率などを測定する。作製した有機EL素子の構成として、以下の構成A(表2)、構成B(表3)、構成C(表4)および構成D(表5)の4つを選定して評価する。構成A~Dはいずれも熱活性化型遅延蛍光用材料に適合した構成である。構成Aは文献(Adv. Mater. 2016, 28, 2777-2781)で示された高い効率を期待できる素子構成である。構成Bは文献(Scientific Reports, 6, 2016, 22463)で示された比較的高い効率と長期間の駆動安定性を期待できる素子構成である。構成Cは文献(Thin Solid Films, 619, 2016, 120-124)で示された、構成Aとは異なるホスト材料を適応した素子構成である。構成Dは2018年6月21日および22日に開催された有機EL討論会第26回例会において発表番号S4-2において発表された長寿命を期待できる素子構成である。ただし、本発明の化合物の適用はこれらの構成に限定されず、各層の膜厚や構成材料は本発明の化合物の基礎物性によって適宜変更することができる。
