Description
本願は、2010年5月21日に出願された米国仮出願第61/347,091号の利益を主張するものであり、すべての図、表および図面を含む当該出願の開示内容は、出典明示によりすべて本明細書に組み入れられる。
仕込みモノマー比が異なる、−[(D)xA]n−構造を有する一連のランダム共役コポリマーを、図1に示す反応を用いて製造し、以下の表1にまとめた。種々のコポリマーの吸収スペクトルを図2に示す。コポリマーPS−3−s1およびPS−3−s2は、表1および図2cに示すように、分子量(Mn)、PDIおよび溶液吸収については、PS−3のそれと矛盾しない結果を示している。モノマーの仕込み比を調整することにより、コポリマーの吸収パターンに対する有効で矛盾のない指示手順が達成された。本発明の態様に基づく共重合方法により、一貫した分子量と光学スペクトルが得られた。
