Karazin popup.description2 The main aim of this investigation is the design and physico-chemical investiga-tion of the new Oxygen- and Nitrogen-containing fluorophores with intramolecular proton transfer and design of chemosensors on their background.The object of investigation - Oxygen- and Nitrogen-containingheterocyclic fluo-rescent compounds with proton transfer reaction and ability to form complexes with polyvalent metals ions. Chemosensing materials on their background. The subject of investigation - excited state proton transfer reaction along the in-tramolecular hydrogen bond and effects in the absorption and fluorescence spectra, connected to it. The general fundamental problem, on resolving of which this work is directed - application of the excited state intramolecular proton transfer reaction of organic con-jugated molecules for development on its background new chemosensing materials including nanosized ones. Determination of the chemosensing ability of the obtained compounds and materials. The specific fundamental task within the general problem, which was tried to re-solve in this work - computer design and organic synthesis on its base of or=ganic compounds with chromone, pyronochromone, oxazole moieties with proton donor and proton acceptor substituents, which are connected one to another by intramolecu-lar hydrogen bond and capable to change their protolytic characteristics in the excited state, which is the driving force of the excited state proton transfer reaction. Determi-nation of the spectral characteristics of the synthesized compounds, their sensitivity to the microscopic parameters of environment. Experimental and theoretic investiga-tion of proton transfer reaction and its effect to the spectra of the investigated com-pounds. Evaluation of the effect of association with biologic systems and complex formation with polyvalent metals ions in solutions and on the solid surface of organic and inorganic nature onto the proton transfer reaction.
