The assembly of a TiO2 surface with π-conjugated mols. can give rise to an apparent red-shift of its optical absorption band, and subsequently engender ligand-to-metal charge transfer (LMCT) triggered by visible light. However, the application of LMCT remains elusive due to the vulnerability of these π-conjugated mols. at the vicinity of reactive centers. Therefore, extending the π-conjugation of these mols. was envisioned to overcome this bottleneck with the oxidation of sulfides as a probe reaction. With salicylic acid as the starting mol., extending the benzene ring at 5,6 or 3,4 positions with another one afforded 2-hydroxy-1-naphthoic acid and 1-hydroxy-2-naphthoic acid . Compared to salicylic acid, 2-hydroxy-1-naphthoic acid showed a moderate improvement, while 1-hydroxy-2-naphthoic acid caused a significant enhancement for modifying anatase TiO2 to conduct the selective aerobic oxidation of sulfides triggered by blue light with (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) as a redox mediator. Ultimately, the aerobic oxidation of organic sulfides to corresponding sulfoxides in CH3OH was achieved by the 1-hydroxy-2-naphthoic acid-TiO2 photocatalyst in cooperation with TEMPO. This study introduces the assembly of extended π-conjugated mols. on TiO2, which may pave the way to construct more efficient visible-light photocatalysts.
