Kucherenko M.G., Ignatiev A.A., Zholud A.A. LUMINESCENCE OF ORGANIC MOLECULE, CONNECTED WITH POLYMERIC CHAINS IN GROUTS: KINETICS OF TRANSFER OF ENERGY TO QUENCHERS AND QUANTUM YIELD OF FLUORESCENCE, DIRECTED BY CONFORMATIONAL TRANSITION. Peculiarities of energy transfer of electric motivation between molecule probes, sorbed on polymeric chain in grout. The description of kinetics of the process is made taking into account stohastic changes of conformation of macromolecule. The results of numerical designing of the problem, and also analytical expressions, received in the context of theory of perturbationfor the case of small speed of transfer and/ or quick conformational movement of macrochain are given. The channel of nonlinear disactivation in the result of pair annihilation of closely set motivated centers were viewed. Expressions for efficient speed of reciprocal quenching and annihilated slow fluorescent probe are received, designed charts of temporal dependencies of characteristic luminescence signals, parametrical curves of relative quantum yield of fluorescence are represented, and also results of experiments on quenching of fluorescence of painted grouts of synthetic polymers and protein.
