本発明の一態様は、下記構造式(1)〜(107)で表されるスチルベン誘導体である。ただし、本発明のスチルベン誘導体は以下の構造式に表されるものに限定されるものではない。
一般式(G7)で表される本発明のスチルベン誘導体の合成方法について、以下に説明する。なお、本発明のスチルベン誘導体は、本実施形態に記載した合成方法に限定されるものではなく、その他の合成方法によって合成しても良い。
本実施形態では、上述した一般式(G1)においてA1とB1とが異なる構造で表される本発明のスチルベン誘導体の合成方法について説明する。なお、本発明のスチルベン誘導体は本実施形態に示す合成方法に限定されるものではなく、その他の合成方法によって合成しても良い。
本実施形態では、上記一般式(G2)で表される本発明のスチルベン誘導体の合成方法について説明する。なお、本発明のスチルベン誘導体は本実施形態に示す合成方法に限定されるものではなく、その他の合成方法によって合成しても良い。
本発明のスチルベン誘導体を用いた発光素子の態様について、図1を用いて説明する。
本発明の発光素子は、複数の発光層を有するものであってもよい。複数の発光層を設け、それぞれの発光層からの発光を混合することで、例えば白色光の光を得ることができる。本実施形態では、このような発光素子について図2、3を用いて説明する。
本実施形態では、本発明を適用した発光装置について図4を用いて説明する。なお、図4(A)は、発光装置を示す上面図、図4(B)は図4(A)中A−A’線断面図(A−A’で切断した断面図)である。図4(A)、(B)のそれぞれにおいて、対応するものは同一の符号を用いて表している。400は基板、点線で示された401は駆動回路部(ソース側駆動回路)、402は画素部、403は駆動回路部(ゲート側駆動回路)である。また、404は封止基板、405はシール材である。
本実施形態では、本発明を適用したパッシブマトリクス型の発光装置について図5(A)、(B)を用いて説明する。図5(A)、(B)は、それぞれ本発明を適用したパッシブマトリクス型の発光装置の斜視図と上面図である。なお、図5(A)は、図5(B)の点線508で囲まれた部分について斜視した図である。図5(A)、(B)のそれぞれにおいて対応するものは同一の符号を用いて表している。図5(A)において、第1の基板501上には複数の第1の電極502が並列に設けられている。第1の電極502のそれぞれの端部は、隔壁層503で覆われている。最も手前に位置している第1の電極502においても端部は隔壁層503によって覆われているが、図5(A)では第1の基板501上に設けられた第1の電極502と隔壁層503とが配置されている様子を分かり易くする為に図示していない。第1の電極502の上方には複数の第2の電極505が、第1の電極502と交差するように並列に設けられている。なお、第1の電極502と第2の電極505との間には発光物質を含む層504が設けられている。第1の電極502と第2の電極505とが交差した部分は、電極間に発光物質を含む層504を挟んでなる、本発明の発光素子を構成している。発光物質を含む層504に、一般式(G1)または(G2)で表されるスチルベン誘導体のうちの少なくとも1つを有する発光層を有していていれば、その他の層の積層構造については特に限定されない。なお、第1の電極502、発光物質を含む層504、及び第2の電極505は、実施の形態5に記載した各々の材料を適宜選択して用いることができる。また、第2の電極505の上には第2の基板509が設けられている。
本実施形態では、本発明の発光素子を有する発光装置を用いて完成させた様々な電子機器について説明する。本発明の発光装置は、本発明のスチルベン誘導体を発光物質として用いることによって、良好な色純度の青色を発光することができる。そのため、さらに色彩に優れた画像が表現可能な電子機器を得ることができる。
構造式(13)で表される(E)−4,4’−ビス[4−(カルバゾール−9−イル)フェニル]スチルベン(略称:CzP2S)の合成方法について説明する。
構造式(22)で表される(E)−4,4’−ビス(9−フェニルカルバゾール−3−イル)スチルベン(略称:PCz2S)の合成方法について説明する。なお、PCz2Sを合成するに際し、必要となる(E)−4,4’−ジブロモスチルベンについては実施例1に示したのでここでは省略する。
構造式(12)で表される(E)−4−(9−フェニルカルバゾール−3−イル)スチルベン(略称:PCzS)の合成方法について説明する。なお、PCzSを合成するに際し、必要となる(4−ブロモベンジル)トリフェニルホスホニウムブロマイドについては実施例1に示したのでここでは省略する。
構造式(3)で表される(E)−4−(カルバゾール−9−イル)スチルベン(略称:CzPS)の合成方法について説明する。なお、CzPSを合成するに際し、必要となる4−(カルバゾール−9−イル)フェニルボロン酸については実施例1に、(E)−4−ブロモスチルベンについては実施例3に示したのでここでは省略する。
