A typical 1,2,3-triazoles are important aromatic heterocyclic compounds with three adjacent nitrogen atoms. These "unnatural" heterocycles found applications in pharmaceutical science, material science and chemical biology. Oligo-1,2,3-triazole linked molecules showed interesting applications in the field of DNA binding, selfassembly, surface modification, supramolecular chemistry etc. In this article, oligo-1,2,3-triazoles are broadly classified into two categories: (i) 1,2,3-triazoles are connected through varieties of organic molecules and (ii) triazole units are connected with one another either by N-(CH)n-C linkages or by amide bonds generated from amino acids. Syntheses and properties of some of these oligomers are reviewed in this article.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
