以下のスキームに従って、化合物5を合成した。
以下のスキームに従って、化合物6a-6dを合成した。但し、化合物6aは、合成方法は異なるものの化合物2と同じであるため、以下には代表例として化合物6bの合成方法を詳しく説明する。
2-ブロモ-3-ヨードナフタレン(5mmol), 4-(N,N-ジフェニルアミノ)フェニルアセチレン(5.25mmol),Pd(PPh3)4(0.10mmol),CuI(0.10mmol),トルエン(10mL)及びi-Pr2NH(5mL)の懸濁液を室温で20時間攪拌した。その後、濾過により無機塩を除去し、すべての揮発性物質を減圧下で蒸発させた。シリカゲルクロマトグラフィ(溶出液はヘキサン/CH2Cl2=4/1)により分離したあと、 得られた粗生成物をMeOHから再結晶することにより精製し、白色粉末である合成中間体M8bを収率96%で得た。
合成中間体M8cは、4-(N,N-ジフェニルアミノ)フェニルアセチレンの代わりに2-(2,3,6,7-テトラヒドロ-1H,5H-ベンゾ[ij]キノリジン-9-イル)アセチレンを用いた以外は、合成中間体M8bの合成方法に準じて合成した。また、合成中間体M9cは、合成中間体M8bの代わりに合成中間体M8cを用いた以外は、合成中間体M9bの合成方法に準じて合成した。更に、化合物6cは、合成中間体M9bの代わりに合成中間体M9cを用いた以外は、化合物6bの合成方法に準じて合成した。この化合物6cは、N上のアルキル基がアニリンのベンゼン環に結合してアルキレン鎖(プロピレン鎖)を形成した化合物の一例といえる。化合物6cのスペクトルデータは以下の通り。

合成中間体M9a(1.24mmol)を無水トルエン(5mL)に懸濁させた懸濁液へ、HSiCl3(6.24mmol)を室温で一度に加えた。1時間攪拌後、すべての揮発性物質を減圧下で除去した。その後、トルエン(5mL)を加え、得られた懸濁液をアルゴン雰囲気下、セライトプラグを通して濾過し、トルエン(5mL)でリンスした。濾液を濃縮後、得られた固体を無水THF(15mL)に溶かした。この溶液へt-BuLiのペンタン溶液(1.77M,1.47mL,2.60mmol)を-78℃で10分かけて添加した。1時間攪拌後、ベンゾフェノン(2.74mmol)を一度に加え、得られた混合液を室温まで6時間かけてゆっくり温めた。その後、NH4Clの飽和水溶液(2mL)を用いて0℃で反応をクエンチし、続いてH2O2水溶液(1mL,30%)で酸化し、室温で1時間攪拌した。Na2SO3水溶液(20mL,10%)で反応をクエンチした後、混合液をEtOAc(50mL)で2回抽出した。合わせた有機層をH2O(20mL),ブライン(20mL)で洗浄し、その後無水Na2SO4で乾燥し、濾過した。濾液を減圧下で濃縮後、得られた固体をシリカゲルクロマトグラフィ(溶出液はCH2Cl2 からCH2Cl2/EtOAc=2/1へ切り替えた)及びGPC(CHCl3)で精製し、薄黄色の固体である合成中間体M10aを収率51%で得た。
合成中間体M10bは、合成中間体9b(0.500mmol)と4,4’-ビス(トリ(エチレングリコール)モノメチルエーテル)ベンゾフェノン(0.600mmol)を出発原料として、合成中間体M10aと同様にして合成した。また、化合物7bは、合成中間体M10aの代わりに合成中間体M10bを用いた以外は、化合物7aと同様にして合成した。化合物7aのスペクトルデータは以下の通り。
化合物1~3,6b~6d,7a及び7bにつき、光物性を測定した。紫外可視吸収スペクトルは紫外可視近赤外分光光度計UV-3150(島津製作所)を、蛍光スペクトルは分光蛍光光度計F-4500(日立)を用いて測定した。絶対蛍光量子収率の測定には、絶対PL量子収率測定装置C9920-02あるいはC11347-01(浜松ホトニクス)を用いた。全ての試料は,ナカライテスク製の蛍光スペクトル測定用溶媒を用いて試料溶液を調製し、1cm角の石英セルを用いて測定した。試料濃度は、吸収スペクトル測定時は約10-5M、蛍光スペクトル測定時は消光が生じないことを確認した濃度の範囲内に設定した。絶対蛍光量子収率を測定する際には、アルゴンを数分間吹き込むことで溶存酸素を除いた。その結果を表1~表8に示す。なお、表には示さなかったが、ヘキサン、酢酸エチル及びメタノールの配向分極率△fは、それぞれ-0.000518、0.201及び0.309であった。
化合物1~3につき、表1~3の結果を用いて、溶媒の配向分極率Δfとストークスシフト値との関係を求めた。その結果を図1に示す。配向分極率Δfは、溶媒の誘電率εと屈折率nを用いて図1に示した式にしたがって算出した。ストークスシフト値は、吸収極大波長λmaxを単位cm-1となるように換算した値から、発光極大波長λexを単位cm-1となるように換算した値を引いた値とした。図1から明らかなように、化合物1~3は、いずれもストークスシフト値と配向分極率Δfとの関係は直線関係(1次関数)に近似できた。このことから、化合物1~3を蛍光色素として利用した場合、λmaxとλexを測定してストークスシフト値を求めれば、それに対応した配向分極率Δfを一義的に導くことができる。つまり、ストークスシフト値から、その蛍光色素の周囲の環境がどのような極性であるかを知ることができる。

ジメチルスルホキシドを0.1%含む化合物1の10mM水溶液中でHeLa細胞を37℃で24時間培養したのち、3%スクロース水溶液で細胞を洗浄し、顕微鏡観察を行った。観察には、ZEISS社の共焦点顕微鏡システム(LSM780)を用いた。その結果、核を除く細胞全体の染色が認められた。ピクセル毎の蛍光スペクトルを取得した結果、530nm、550nm、および565nmに発光極大をもつ3種類のスペクトルに分類できた。細胞の表層付近は主に530nm、細胞質の部分は565nmに極大をもつ発光を示し、細胞質中には550nmに発光極大をもつ箇所が点在していることが認められた。染色された細胞組織の極性環境に依存して発光色が異なることを反映しているものと考えられ、同一の化合物1を用いて細胞内環境のイメージングが可能であることが示された。
ジメチルスルホキシドを0.001%含む化合物3の100nM水溶液中で、HeLa細胞を37℃で1時間培養したのち、3%スクロース水溶液で細胞を洗浄し、顕微鏡観察を行った。観察には、ZEISS社の共焦点顕微鏡システム(LSM780)を用いた。その結果,核を除く細胞全体の染色が認められた。ピクセル毎の蛍光スペクトルを取得した結果、520nmおよび570nmに発光極大波長をもつ2種類のスペクトル分類された。この結果より、染色されている部位に応じて発光波長が異なることが分かった。
化合物1,2(6a),6b,7a,7b及び公知の蛍光色素Alexa-430の各々につき、吸光度が同程度(0.39~0.44)になるようにアセトニトリル溶液を調製した。溶液中の化合物の濃度は、化合物1:2.35×10-5M,化合物2(6a):2.17×10-5M,化合物6b:1.25×10-5M,化合物7a:3.30×10-5M,化合物7b:2.04×10-5Mであった。Alexa-430は耐光性の高い蛍光色素として知られている。各アセトニトリル溶液につき、溶液調製直後にモル吸光係数を測定した。その後、各アセトニトリル溶液に403nmのレーザ光を20分、60分、120分照射した後のモル吸光係数を測定し、レーザ光照射前(溶液調製直後)のモル吸光係数に対する相対吸光度を求めた。その結果を図2に示す。図2から明らかなように、化合物1,2(6a),6b及び蛍光色素Alexa-430と比べて、化合物7a,6bはレーザ光を120分照射した後も相対吸光度はほぼ1のままであり、非常に高い耐光性を示した。
