Z-E photoisomerisation of styrene- and stilbene-derived push-pull systems bearing 4,5-dicyanoimidazole unit.
Z-E isomerisation of six styrene- and stilbene-derived chromophores featuring 4,5-dicyanoimidazole unit was investigated. The photo-isomerisation was induced by irradiation of the chormophore in ethyl acetate. The observed photo-
