Abstract:
The photocatalytic reaction is regarded as an efficient and sustainable strategy to convert solar energy into chemical energy. In the work, a novel metal–organic framework Zn 5 (TPyP)(BCTC) 2 (H 2 O) 3 (denoted as CCNU-16, H 2 TPyP = 5,10,15,20-tetra(4-pyridyl)-21 H ,23 H -porphine, H 4 BCTC = [9,9′-bicarbazole]-3,3′,6,6′-tetracarboxylic acid) was successfully synthesized from porphyrin- and carbazole-based organic linkers, which exhibits excellent visible-light-responsive characteristic. CCNU-16 was further applied toward photo-induced aerobic oxidation of amines and sulfides in air under visible light illumination and ambient conditions. Outstandingly, the turnover frequency (TOF) of the photocatalytic oxidative coupling of benzylamine over CCNU-16 is at the high end among MOF-based photocatalysts, so far, even under green and mild conditions. The excellent photocatalytic activity is attributed to superoxide radical anion (O 2 ˙ − ) and singlet oxygen ( 1 O 2 ) generated by the synergistic charge transfer (CT) and energy transfer (ET) processes, which provide a reasonable and efficient method for the photocatalytic oxidation of organic transformations.
