synthesis of novel bibenzimidazole oligomers and polymers is reported here using methyl 2,2,2-trichloroacetimidate as a key starting material. The dimer, trimer, tetramer, and polymers of bibenzimidazole were synthesized as a new series of potential conjugated chelating ligands for metallopolymer studies. The polymers show a maximum absorption at around 400 nm. The optical band gap of the polymer was estimated
本文报道了一种简单,温和的缩合路线,用于合成新型联苯并咪唑低聚物和聚合物,使用2,2,2-三氯乙亚氨酸甲酯作为关键原料。合成联苯并咪唑的二聚体,三聚体,四聚体和聚合物,作为用于金属聚合物研究的一系列潜在的共轭螯合配体。该聚合物在约400nm处显示出最大吸收。聚合物的光学带隙估计为2.68eV。
