摘要：

Two series of compounds, 3-aryl-(series A, compounds 2a-j) and 3-methyl-7-aryl-[1,2,3]triazolo[1,5-a]pyridines (series B, compounds 3a-j) have been synthesized by Suzuki cross-coupling reactions, with a triazolopyridine halide and an aryl or heteroaryl boronic acid in moderate to good yields. All compounds obtained are fluorescents, the quantum yields, particularly those of compounds 3f-f, are very high. (c) 2006 Elsevier Ltd. All rights reserved.
