Photocatalysis utilizing the renewable and sustainable energyof visible light holds intrinsic advantages in the aspects of bothmild reaction conditions and product selectivity and hence isgrowing into a powerful tool in organic synthesis.29−32 Metal(RuII, IrIII, ReI, and OsII) polypyridine complexes and organicdyes are two typical categories of photocatalysts that haveattracted intense research interests.33−37 Metal−organic frameworks (MOFs) have demonstrated their success as heterogeneous catalysts in organic transformations, whereas theirapplications in heterogeneous photocatalysis have beenscarce.2
