The synthesis and photochromic mechanism of 4-aza-15-crown-5-4'-methoxya-zobenzene and 4-aza-15-crown-5-4'-nitroazobenzene were described. It was found that the photochromic mechanism of these two compounds was the photo-inducing twisted in-tramolecular charge transfer and was not cis-trans isomerization.
