Abstract
Spectral and luminescent properties of two photobifunctional compounds (PBC) were studied, whose molecule includes spirocyclic naphthopyran or naphthoxazine and hydroxyazomethine fragments bound together by different ways, in comparison with model compounds. Temperature and solvent dependences of the luminescence spectrum for PBC 1 and the absence of such dependences for PBC 2 were found. Selective excitation of PBC 1 with enol or cis-keto form of the azomethine fragment leads to the same luminescence spectrum at 293 K.
