Aim of the work - Development and improvement of methods for macroheterocycles (MHC) synthesis and their acyclic analogues, containing fragments of benzimidazole, studying features of these compounds interaction with aerosil (AS) surface, modified MHC. Detection features of similar compounds complexation with ions of s-, p , d- and f- metals. Investigation of optical (luminescence, fluorescence) properties of obtained ligands and metal complexes. Objects of research - MHC and podands, containing fragments of benzimidazole. Methods of research: elementary analysis, IR-spectroscopy, mass spectrometry, PMR-spectroscopy, UV-spectroscopy, luminescence spectroscopy. It was found, that derivatives of imidazole-4,5-dicarboxilyc acid (DIDCA) observed Stokes shift (>9000 cm-1). It is shown that lanthanide complexes with DIDCA are capable to sensibilization of 4f-luminescence in visible [Eu (III) and Tb (III)], and in near IR-region [Nd (III) and Yb (III)]. Features of MHC sorption (total 10 compaunds) with benzene solutions on aerosile A-300 (AS) and aminopropilaerosile (APA). It was shown that MHC sorption capacity with fragments is determined not so much by atoms nature in bridges, but by distance between main H-acceptor centers. AS samples were obtained with immobilized on surface complexes of benzimidazole derivatives with 3d- and f metals.
