含蒽醌酰亚胺基元的旋光性聚乙炔及其近红外性质
DOI: 10.3724/SP.J.1105.2013.13029, PP. 443-449
Keywords: 蒽醌酰亚胺,光学活性聚合物,近红外电致变色,聚乙炔
Abstract:
用改进的方法合成了6-溴蒽醌-2,3-二羧酸酐,制备出一个新的非手性炔类单体——N'-(1-己基庚基)-6-乙炔基蒽醌-2,3-二羧酸酰亚胺,并在铑配合物的催化下得到相应的聚合物.当在催化体系中加入手性1-苯基乙胺时,所得的聚合物具有旋光活性,在紫外吸收区具有明显的Cotton效应.聚合物保持了蒽醌酰亚胺基元的近红外电致变色性质,对其施加-0.6V的电压后,在500~1200nm波长范围出现了明显的吸收谱带,最大吸收波长为820nm.
