で洗浄され、無水性MgSO4で乾燥され蒸発された。カラムクロマトグラフィー(ヘキサン)による純化により、表題の化合物(1.45g,15%)を非白色固体として生成した。(実測値:C,25.8;H,1.0;C12H6Br2I2の理論値はC,25.6;H,1.1%);mp89℃;νmax/cm-1(固体)710、817、993,1086,1448,1565;δH(400MHz,CDCl3)7.03(2H,d,J8.2,ArH)、7.55(2H,dd,J8.2,1.9,ArH),8.08(2H,d,J1.9,ArH);δc(100MHz,CDCl3)99.8,122.5、

ポリマーの実施例1:本発明の第1の側面のホモポリマーは、次のスキームにしたがってモノマー1及びモノマー2のスズキ重合により、続いて、ブロモベンゼン及びフェニルホウ酸の末端キャップが行われ製造された。
一般的方法:ガラス基板(Applied Films, Colorado, USAより入手可)に支持されたインジウム錫酸化物上にHC Stark of Leverkusen, GermanyからBaytron P(登録商標)として入手できるPEDT/PSS層をスピンコートにより蒸着した。電子発光ポリマー層はキシレン溶液からスピンコートによりPEDT/PSS層上に蒸着された。電子発光ポリマー層上には、カルシムの第1層及びアルミニウムの第2キャップ層からなるカソードが真空蒸着された。

本発明の第9の側面のモノマーは、次の反応スキームにしたがって合成された。また、上記2,7結合ジベンゾシロールを有する上記の場合のように、ジメチルシリル基(ステップe)のトランスアルキル化はトリメチルシリル末端基に影響を与えず、したがってこのルートはシリコン原子に広い範囲の置換基を導入する方法を提供する。
下記の表は、コポリマーの吸収最大値及び光学的バンドギャップを示す。コポリマーの溶液UV−Vis吸収スペクトルがヘキサン中で測定された。
bポリマーのバンドギャップ、UV吸収オンセットからの測定
コポリマーの薄膜が金の実用電極上にサンプル(トルエン中の1.0重量%溶液)をスピンコートすることにより得られた。ついで、室温で50mV/sのスキャンレートで、対極電極としてプラチナ線、参照電極としてAg/AgCl電極を使用して、アセトニトリル中のBu4N+ClO4 -(0.10M)溶液中で測定された。両測定は、4.8eVのイオン化ポテンシャルを有するフェロセンに対して較正(キャリブレーション)された。
