K. Pitchumani et al., TRIPLET-TRIPLET ENERGY-TRANSFER BETWEEN ORGANIC-MOLECULES TRAPPED IN ZEOLITES, Chemical communications, (17), 1996, pp. 2049-2050
Double loading of a zeolite with a triplet energy donor and a triplet
energy acceptor followed by selective irradiation into the donor absor
ption band leads to characteristic triplet state reactivity of the acc
eptor.
