Abstract

Absorption and fluorescent spectra of imidazo-[4,5-d]-phenazine and its three novel derivatives were studied in ethylacetate and glycerole. Absorption spectra of these derivatives in visible region consist of two bands attributed to different ππ* electronic transitions. Energy values of S1<—S0 electronic transition are calculated for all derivatives. Fluorescence polarization degrees of 2-trifluoridemethylimidazo-[4,5-d]-phenazine and 1,2,3-triazole-[4,5-d]-phenazine are several times higher of that for unsubstituted imidazophenazine, that makes perspective their using as fluorescent probes upon studies of nucleic acid molecular hybridization.
