The spectroscopic characteristics of both compounds in 23 solvents with different polarities or hydrogen-bonding donor (HBD) abilities has been studied as a function of three solvatochromic parameters (ET(30), π* and α). Both compounds 1 and 2 showed a pronounced bathochromic shift of the main absorption band on increasing solvent polarity and HBD ability. The correlation is better for compound 2 than for compound 1. The stronger effect and better correlation was observed for compound 2 with the increment of the solvent HBD ability (α parameter).Reconocimiento (by)Triarylmethane dyesCrystal structureSolvatochromic studiesPROYECTOS DE INGENIERIAArtículo10.3390/molecules201119724Abierto26610444PMC6332080
