Excited electron states and photoprocesses in series of oxazoles and oxadiazoles

Quasihomologous series of complex N, O, S-heteroaromatic molecules has been considered in the work. The purpose of the paper is to determine the interaction of structure, density matrix structure, nature of excited electron states and transitions, spectral, luminescent and generation properties of complex multiatom molecule series. A principle of a quasiautonomous role of subsystems from different sets of which a complex molecule structure is constituted in processes of an intermolecular transformation of electron-vibratory excitation power has been formulated and proved. A method of a priori-structural modelling of molecules has been offered. Seventeen new complex molecules which are capable to fluoresce and generate radiation in ultraviolet and visible spectrum regions to regions of 335-560 nM long waves have been revealed by a priori-structural modelling method. New molecular formations - tricyclic bis-oxazoles and oxadiazoles - base central fragments with practically important properties have been foundAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
