- Abstract
A coumarin-derived compound, 3-benzoyl-7-hydroxy coumarin (BHYC), is synthesized to determine its optoelectronic properties, including absorbance band edge, optical band gap, transmittance, refractive index, electrical susceptibility, volume-surface energy loss functions and optical/electrical conductance parameters. The absorbance spectra of BHYC in dimethylformamide (DMF) and dimethylsulfoxide (DMSO) solvents exhibit maximum peaks at 350 and 353 nm, respectively, in the nearultraviolet region. The absorbance band edge values of BHYC in DMF and DMSO are 2.526 and 2.500 eV, respectively. The optical band gap of BHYC varies from 2.560 to 2.408 eV with increasing molarity. In contrast, the refractive index of BHYC increases from 2.47 to 2.95 with changing molarity. The obtained results show that 3-benzoyl-7-hydroxy coumarin exhibits a semiconductor behavior and it may be an important candidate for many optoelectronic devices, such as diodes, photodiodes and sensors.
