Paper Abstract

The photophysical properties of some new and also some known complex organic molecules emission and generated radiations in the wavelength interval ▵λmax osc,fl ≈ 340-760 nm have been studied in a wide range of organic solvent. Specifically, these molecules are based on phenyl-, furyl-, thienyl-oxazoles and oxadiazoles to compile a quasihomological series. Using the measured values of the extinction (εvabs), the fluorescence quantum yields (γ fl), and the fluorescence lifetime (τ fl), we calculated rate constants for radiative decay (k fl), and intercombination conversion (kST), along with the cross sections for absorption (σmax13), and stimulated emission of radiation (σosc31). We also found the longest limit pump-pulse rise time (tlp) for which generate of the oscillations active molecules. Within the framework of the method of spectral-quantum-chemistry modeling LCAO-MO CSF CI INDO/S, CNDO/S, and PPP/S of structure and optical and nonoptical properties for the multiatomic molecules.
