Phototransformation of benzimidazole and thiabendazole inside cucurbit[8]uril
Original language description
The phototransformation of benzimidazole (BZ) and of the benzimidazole pesticide thiabendazole (TBZ) was investigated in aqueous solution in the absence and presence of the supramolecular host cucurbit-[8]uril (CB8). ESI-MS and NMR reveal that both compounds form stable 1 : 2 host-guest complexes with CB8 (BZ(2)@CB8, TBZ(2)@CB8). The phototransformation of free BZ leads to dehydrodimerization, while for TBZ the photoreactivity leads to BZ, benzimidazole-2-carboximide and 2-acetylbenzimidazole. Inside CB8, BZ undergoes photohydrolysis to form 2-aminoformanilide, while for TBZ(2)@CB8 additional photoproducts were observed which are pH dependent. At pH 1.2 photolysis of TBZ(2)@CB8 leads to new red-shifted photoproducts with extended p conjugation.
