Triazole- and Thiadiazolecontaining Macroheterocycles: Review of Main Achievements for Last Decade

摘要

The work reviews main achievements of last decade in the field of .synthesis and properties research of macroheterocyclic compounds of ABBB- and AABAAB-types, A being 1,2,4-triazole, 1,24- or 1,3,4-thiadiazole moiety, and B being (un)substituted isoindoline resudie. All the compounds were obtained through interactions between heterocyclic di amine and 1,3-diiminoisoindoline or phthalonitrile under different conditions. The ABBB-type target products have properties of "molecular chameleons"; in other words, they possess an unique ability to postsynthetically modifj, the molecular optic properties. The AABAAB-type products as macroheterocyclic compounds with an expanded coordination cavity allow to insert one large and several smaller metal atoms into an intramolecular cavity. Therefore, the compounds become potential anion receptors. Moreover, a bathochromic shift of maximum absorption band into infra-red region of electron spectra of AABAAB macroheterocycles with expanded conjugated r-electron system can promote their use as photodynamic therapeutic agents.
