Significance

A triazine-based covalent organic framework bearing thiophene units CTF-Th-0 was found to promote the photocatalytic oxidation of toluenes with molecular oxygen under blue LED ­irradiation to give the corresponding benzaldehydes. Alkylbenzenes gave acetophenones under similar conditions.


 

Comment

A series of CTF-Th-X was prepared through the super acid-catalyzed polymerization of dicyanothiophenes Th-0, -1, -2, respectively, with a silica template. In the photooxidation of toluene, used CTF-Th-0 was recovered by centrifugation and reused four times without a significant loss of its catalytic performance.
