The pale yellow crystals of fulgides 5a, 5b, 5c, 5d and 5e in crystalline state and in solutions, change to red on irradiation at 366nm, this change is reversed on exposure to white light. The substituents on the methylene group have a remarkable effect on the absorption maxima of both the coloured and uncoloured forms.
