Quantum dot gels as efficient and unique photocatalysts for organic synthesis.

ABSTRACT: Here we report CdS quantum dot (QD) gels as highly efficient and unique photocatalysts for organic synthesis. We found that the photocatalytic activity of CdS QD gel was superior to phosphine oxide- and thiolate-capped CdS QDs for dehalogenation and α-amine arylation reactions because of the high accessibility of its surface sites to the substrates. In addition, we discovered the unique reactivity of CdS QD gel for ring-opening during α-amine arylation of tetrahydroisoquinoline via the reductive cleavage of C-N bonds. QD gels provide new opportunities in photocatalysis due to their unique surface interactions with the substrates or intermediates.
