三量体の調製
置換プライマーの調製
出発原料を換え、かつ実施例1と同様の方法を介して、実施例1、2にて調製した三量体の置換種を調製した。代替して使用した出発原料の調製方法の例は、下記の通りである。
高分子の調製
F8−ジエステル(9.546g、18mmol)、ジブロモ−BT(2.646g、9mmol)、「三量体1」(4.109g、9mmol)、テトラキス(トリフェニルホスフィン)パラジウム(0)(60mg)がトルエン(180ml)に添加された懸濁液を、窒素で脱ガスした。1時間後、テトラエチルアンモニウム水酸化物(60ml)を反応混合物に添加し、外部温度がおよそ115℃となるまで懸濁液を加熱した。正確に4時間20分後、ブロモベンゼンによって末端基を付加した。115℃で1時間撹拌した後、フェニルボロン酸(2.5g)を添加して、さらに1.5時間撹拌を続行した。反応混合物を室温に冷却した後、メタノール(4リットル)に高分子を析出させた。高分子を濾過して、トルエン(500ml)に再溶解した。ジチオカルバミン酸(30g)の水溶液(220ml)をトルエン溶液に添加した。塩混合物を65℃で18時間加熱した後、水溶液層を除去した。有機物層をアルミナ/シリカカラムに通過させ、トルエンで高分子を抽出した。トルエンを350mlに濃縮して、メタノール(4リットル)に析出させた。高分子を濾過して、充分に乾燥した。
光学素子
好適な素子構造を図1に示す。陽極2は、ガラス製またはプラスチック製の基板1上に担持された、インジウム−スズ酸化物(ITO)からなる透明な層である。アノード2の層の厚みは、1000〜2000Åであり、一般的にはおよそ1500Åである。陰極5は、Ca層からなり、その厚みはおよそ1500Åである。両電極の間には、厚みがおよそ1000Åまでの発光層4が介装されている。発光層4は、本発明に係る高分子を0.5〜30重量%含有する。発光層4の残部は、正孔あるいは電子のいずれかを輸送する材料、および/または、発光材料である。なお、素子は、厚みがおよそ1000ÅのPEDOTからなる正孔輸送層3を具備することが好ましい。層6は、適切な厚みの被覆層である。
