摘要：
The method of synthesis of unsymmetrical azomethynes-bifluorophores where one of the fluorescent fragments is a donor of electron excitation energy and the second one is an acceptor was worked out. Photophysical properties of azomethynes-bifluorophores were investigated. It was shown that in these compounds non-radiative energy transfer takes place. It was established that quantum-chemical semiempirical method AM1 may be used for the calculation of spatial structure of amines-fluorophores.
