Abstract

We have shown previously that photoexcited phenazine doped as acceptor in a fluorene single crystal is able to abstract a hydrogen atom from the methylen group of a specific neighbor host molecule. Reaction product is a radical pair (RP) triplet state the molecular structure of which is known in detail /l/. Precursor is the photoexcited triplet state of the phenazine acceptor. The H-transfer is fully reversible. At room temperature the RP product has a lifetime of only ~0.2 μs.
