Abstract
Oxadiazole-indole hybrids are interesting molecules and show excellent photophysical properties emitting light in the visible region. In the present study, the photophysical property of a series of indole-oxadiazole hydrazides 8a-f and their sugar-hydrazones 9a-f were investigated. All studied molecules were characterized using ATR-IR, 1H NMR, 13C NMR, and mass spectrometry. The optical properties of compounds were studied using UV–visible and photoluminescence spectroscopy. Density functional theory (DFT) calculations were done to study the structural properties of hydrazides and their sugar hydrazones. Emission spectra of all compounds showed bands around 385–437 nm with quantum yields ranging from 10.89 to 18.65%. Overall, the obtained results indicate that these compounds could be used as optoelectronic materials in the future.
