IR spectra were recorded on a Bruker Vertex 80V device in the regions of 7500-350 cm(-1) from pellets with KBr. The NMR spectral studies on the nuclei 1H and C-13 were performed on a Bruker Avance-500 instrument (500.13 MHz) in CDC13, the internal standard was TMS. Elemental analyses of crystalline compounds were carried out on a FlashEA 1112 analyzer. Mass spectra were registered on a JMS-700 JEOL (FAB) and JMS-100GCV JEOL (EI) mass-spectrometers. UVN is spectra and fluorescence spectra were recorded on a spectrofluorimeter CM 2203 (SOLAR) in CH2Cl2, with square quartz cavity being 10 mm thick. The fluorescence quantum yield was determined by formula utilizing fluorescein in 0.1 M NaOH as a standard (Phi(s)=0.85).
