Effect of intramolecular exciplex formation upon the photoreactivity of naphthylalkylamines and anthrylalkylamines

Abstract
Several NN-diethyl-1-naphthylalkylamines and NN-diethyl-9-anthrylalkylamines exhibit intramolecular exciplex formation and as a result reactions typical of the hydrocarbon singlet states, e.g. hydrogen abstraction from tertiary amines and dimerisation, are quenched.
