Peroxoborate and the oxidizing cations [Co(NH3)(6)](3+), [Ru(NH3)(6)](3+) and N,N'-dimethyl-4,4'-bipyridinium(2+) (paraquat(2+)) form ion pairs in aqueous solutions which display outer-sphere charge transfer (OSCT) bands in their absorption spectra. This CT involves an electronic transition from the peroxo substituents of peroxoborate to the cations. When 10,10'-dimethyl-9,9'-biacridinium(2+) (lucigenin(2+), LG(2+)) is used as an electron acceptor an OSCT absorption is not observed owing to the instability of the ion pair LG(2+) peroxoborate which undergoes a chemiluminescent conversion to N-methylacridone.
