The reaction of [60]fullerene with 2-diazo-4,5-dicyanoimidazole affords new compound 4 which contains an electron poor aromatic heterocycle attached to the fullerene sphere.
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 chromophore
