Efficient Sensitized Photooxygenation in Water by a Porphyrin−Cyclodextrin Supramolecular Complex

Efficient Sensitized Photooxygenation in Water by a Porphyrin−Cyclodextrin Supramolecular Complex

The 2:1 inclusion complex between (2,3,6-tri-O-methyl)-β-cyclodextrin (TMβCD) and 5,10,15,20-tetrakis(4-sulfonatophenyl)-porphyrin (TPPS4) behaves as a supramolecular sensitizer in water providing photooxygenation with turnover numbers up to 30 000 with a very minor sensitizer bleaching (
