Syzova Z. Synthesis and Reaction Ability of Organic Luminophores – Derivatives of Iminochromene and Cumarin

Investigation objects: organic luminophores - derivatives of iminochromene and coumarin. Purpose: synthesis of systematic series of 3-benzazolyl derivatives of coumarin and 2-iminochromene, elaboration of quantitative interrelations between their molecular structure and resistence to hydrolysis, acid-base properties and spectral-luminescent parameters. Methods: X-ray structural analysis, 1H NMR- and IR-spectroscopy, absorption and fluorescence spectroscopy at stationary and pulse excitation, quantum chemical calculations, lasing action at conditions of flesh lamp pumping. Structural factors and mechanisms, which have effect on the reaction ability, acid-base and spectral-luminescent properties have been estimated. The most prospective for the design of such a new organic luminophores is the utilization of the process of intramolecular electron transfer. Prospects of our compounds for their application to lasing techniques, medical and biological studies have been shown as well. Degree of application:design of new organic luminophores and fluorescent probes sensitive to polarity and acidity.
