“…14 The improvement can be achieved through synthetic routes, including "click" chemistry, 9,[15][16][17] azidealkyne cycloaddition, 18,19 and Sonogashira coupling reactions. [20][21][22] "Click" chemistry is a powerful tool for synthesizing 1,2,3-triazole-based sensors. In this method, azides and terminal alkynes react in the presence of a copper(I) catalyst to form 1,4-disubstituted-1,2,3-triazoles.…”
