✦ Synopsis
Six branched and stable push-pull chromophores featuring 4,5-dicyanoimidazole as an acceptor moiety, an N,N-dimethylamino group as a donor and various p-conjugated linkers are reported. Systematic extension of the p-linker revealed that the optical and electrochemical properties of A-p-D chromophores are mainly affected by the nature of the p-conjugated backbone (length and planarity) as well as by the number of appended donors.
