Title: Characterization of the triplet excited state of the phenylxanthenium carbocation

The triplet–triplet absorption shows λ max ≤ 300 nm and decays over a period of several microseconds in the absence of easily oxidized donors. The triplet cation reacts with 9-phenylxanthydrol and biphenyl via electron transfer to give the corresponding radical and radical cation and also reacts rapidly with both oxygen and 1,3-cyclohexadiene. Keywords: carbocations, triplets, electron transfer, laser flash photolysis.Read More
