A series of N-2 aryl 1,2,3-triazoles were prepared through regioselective post-triazole arylation. The perfect coplanar conformation was observed in X-ray crystal structures, suggested potential photo-activity. The fluorescence of various N-2 aryl triazoles were investigated and a new class of triazole-based fluorophore was revealed with excitation and emission adjustable with different N-2 and C-5 substitution.
