A Study on the Optoelectronic Parameters of 4-Chloromethyl-7-Hydroxy Coumarin in Various Solvents and Concentrations

Adnan KURT [1] , Bayram GÜNDÜZ [2] , Murat KOCA [3]

A coumarin derivative compound, 4-chloromethyl-7-hydroxy coumarin (CMEHC), was synthesized in order to test the concentration and solvent effect on its optical properties. The spectral characterization of this compound was accomplished by FTIR and 1H-NMR techniques. The UV absorption spectra of CMEHC compound in various solvents (THF, DMSO, DMF) were recorded with a UV–VIS spectrophotometer. The optical parameters such as maximum peak position, absorption band edge and direct allowed band gap were reported for these solvents and also various concentrations. The lowest direct allowed band gap was obtained with THF solvent. The absorbance spectra of CMEHC compound were dominant at the near ultraviolet region. The refractive index values were compared with each other using Moss, Ravindra, Herve-Vandamme, Reddy and Kumar-Singh relations.
