Electrogenerated chemiluminescence (ECL) provides an unusually attractive method for producing dimeric luminophors, by comparison to optical pumping of a dye laser, both in terms of dimer/monomer ratio and variety of accessible states. Several dimeric luminophors arising from the homogeneous charge transfer step are discussed, and the customary assignment of full singlet or triplet character to some of the excited moieties is shown to be unwarranted. An error in the literature concerning the kinetics of ECL-dimer formation is pointed out.
