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 pi-conjugated linkers are reported. Systematic extension of the pi-linker revealed that the optical and electrochemical properties of A-pi-D chromophores are mainly affected by the nature of the pi-conjugated backbone (length and planarity) as well as by the number of appended donors.
