Abstract
【解決手段】レジオレギュラーポリアルキルチオフェン及び/又はレジオレギュラーポリ[2,5−ビス(3−アルキルチオフェン−2−イル)チエノ(3,2−b)チオフェン]、並びにメタロセンを含む組成物であって、メタロセンが組成物の全重量を基準にして50重量%より多い量で存在する。
【選択図】なし
Description
以下の構造(I)はHT−HT結合を有し
この実施例は、50重量%以上のメタロセンおよびレジオレギュラーポリチオフェンを有する溶液から製造された導電性組成物が、同じ量のメタロセンを含まない溶液から製造された比較の組成物よりも有意に向上した電荷移動度を示すことを実証するために行われた。
この実施例は、導電性組成物の全重量を基準にして50%より多い量でメタロセンを使用することの利点を詳述しかつ実証するために行われた。特に、この実施例は実施例1と共に、Worleへの米国特許出願公開第2009/0001359A1号のものを超える、請求項に記載された組成物の利点を詳述する。
この実施例は、組成物に対して75重量%より多いフェロセンの量を添加する効果を決定するために行われた。サンプルは実施例1におけるのと同じように製造された。結晶化度および結晶充填を調べるためにx線を用いて5種類の組成物が試験された。これらサンプルは、ポリ(3−ヘキシルチオフェン)のみ(すなわち、ニートのポリ(3−ヘキシルチオフェン))、およびフェロセンとポリ(3−ヘキシルチオフェン)を1:3、1:1、3:1、および9:1の重量比で含む4種類の組成物を含んでいた。
この実施例は、50重量%以上のメタロセンおよびレジオレギュラーポリチオフェンを有する導電性組成物が、同じ量のメタロセンを含まない比較の組成物よりも、有意に向上した電荷移動度を示すことを実証するために行われた。
