A brief minireview of poly-triazole: Alkyne and azide substrate selective, metal-catalyst expansion

Organic compounds that contain poly-triazole are very important intermediates in pharmaceutical and chemical industry. Click chemistry is one of essential reactions that can form CN bond with high atom economy. The research progress in metals catalyzed Click chemistry of azides and alkynes from the perspective of reaction mechanism is categorized and summarized. Given the wide utility of click-chemistry reactions for the selection of alkyne and azide substrate within large architecturally complex materials, this minireview article aims at surveying papers exploring their scope in the area of π-conjugated polymers for application in sensors, drugs to enable advanced functional properties.
