In this work we report solvatochromic and luminescent properties of ethyl -salicylideneglycinate (), ethyl -(5-methoxysalicylidene)glycinate (), ethyl -(5-bromosalicylidene)glycinate (), and ethyl -(5-nitrosalicylidene)glycinate () dyes. - correspond to a class of -salicylidene aniline derivatives, whose photophysical properties are dictated by the intramolecular proton transfer between the OH-function and the imine N-atom, affording tautomerization between the enol-imine and keto-enamine forms. Photophysical properties of - were studied in different pure non-polar and (a)protic polar solvents as well as upon gradual addition of NEt, NaOH, and CHSOH. The DFT calculations were performed to verify the structures of - as well as their electronic and optical properties.
