Scheme S1 Synthesis of reaction intermediates
Synthesis of S1. It was obtained from 4,7-dibromo-2-butyl-2H-benzo[d][1,2,3]triazole (1.00 g, 3mmol) and (4-
formylphenyl)boronic acid (0.400 g, 1 mmol) was kept at 85 °C for 3 h nitrogen atmosphere. On the completion of
reaction (monitored through TLC), the mixture was poured into water and extracted with chloroform. The organic
layer was washed with brine solution followed by water and dried over anhydrous Na2SO4. The volatiles were
removed to obtain a solid residue. The obtained crude product was further purified by column chromatography using
silica as stationary phase and hexane:chloroform (1:1) as eluent. Colorless solid; yield 0.390 g (37%); m.p. 58-60
