Photochromic hybrid compounds based on coumarins with reversible fluorescence modulation have been synthesized for the first time. It was shown that UV irradiation leads to spectral and fluorescent changes due to the structure of the compounds. Keywords: photochromism, naphthopyran, coumarin, spectroscopy, fluorescence, hybrids.
