Abstract: A process of synthesizing hyperbranched polytriazoles, linear and hyperbranched poly(aroyltriazoles) by Huisgen 1,3-dipolar cycloaddition. The polytriazoles were prepared by A2+B3 method to avoid self-polymerization during monomer preparation and storage. The polymers are light emissive and can be crosslinked to generate well-resolution photopatterns upon UV irradiation. White light emission patterns were observed with fluorescence microscopy. The high molecular weight poly(aroyltriazoles) (up to 26000 Da) are prepared in high yields (up to 92.0%) and with high regioselectivity (the ratio of 1,4- and 1,5-disubstituted 1,2,3-triazole is equal or larger than 9:1). The polycyclomerization is not moisture or oxygen sensitive and therefore, no special precautions are necessary before and during the reaction. All the polymers are processible, easily film-forming, and curable into thermosets by heat or irradiation. The hyperbranched polymers can act as fluorescent adhesive materials with large tensile strength.
