The effect of a high magnetic field ( < 14 T) on the intramolecular exciplex fluorescence generated from a phenanthrene and dimethylaniline chain-linked molecule is studied in acetonitrile. On increasing the magnetic field from zero to = 1 T, the fluorescence decay rate decreases steeply and then in
The use of magnetic field effects in delayed fluorescence (DF) and electrogenerated chemihrminescence (ECL) studies to obtain information about the involvement of triplet state species in reactions leading to the production of monomeric and dim&c (excimer or exciplex) excited states is described. In
