Abstract: 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 thephotochromic mechanism of these two compounds was the photo-inducing twisted in-tramolecular charge transfer and was not cis-trans isomerization.

Key words: azobenzene crown ether, photochromism, TICT
