Abstract: A novel coumarin derivative of 4-(4-aminostyryl)-7-methyl-2H-chromen-2-one (5)was synthesized by the reaction of 4-(bromomethyl)-7-methyl-2H-chromen-2-one and p-nitro benzaldehyde using toluene at 120Co via standard Wittig reaction condition. The molecules were characterized by spectral analysis and the photophysical properties for organic electronic applications were examined, such as thermal stability, strong and broad optical absorption and emission studies. Optical properties are explicated by UV-Vis absorption and fluorescence spectroscopy........
Keywords: 4-(4-Aminostyryl)-7-methyl-2H-chromen-2-one, UV-Vis absorption, Thermogravimetry, Photo physical studies, Density functional theory (DFT).
