The copper-catalyzed and metal-free azide-alkyne click polymerizations have become efficient tools for polymer synthesis.However,the 1,3-dipolar polycycloadditions between intal alkynes and azides are rarely employed to construct functional polymers.Herein,the polycycloadditions of dibutynoate (1) and tetraphenylethene-containing diazides (2) were carried out at 100 ℃ for 12 h under solvent-and catalyst-free conditions,producing soluble poly(methyltriazolylcarboxylate)s (PMTCs) with high molecular weights in high yields.The resultant polymers were thermally stable with 5％ weight loss temperatures up to 377 ℃.The PMTCs showed aggregation-induced emission (AIE) properties.They could work as fluorescent sensors for detecting explosive with high sensitivity,and generate two-dimensional fluorescent photopatts with high resolution.Furthermore,their triazolium salts could be utilized for cell-imaging applications.
