✦ Synopsis

Excited-state absorption spectra are reported for the luminescent metal-ligand charge-transfer states of copper(l) complexes wth the hgands 2,9-dimethyl-and 2.9-dlphenyl-l,lO-phenanthroline.

Excited-state lifetimes derived from transient absorbance decay, ground-state recovery or lummescence decay measurements all agree wthin experimental error but exhibit a significant concentration dependence. A kmetlc analysis shows that the phenomenon is attributable to formatIon of dimers of the parent complexes.

## Abstract The ESR spectra of some aromatic charge‐transfer complexes in the lowest excited triplet states were measured. From the extracted zero‐field‐splitting parameters it was found that in each case the lowest excited triplet state was localized on the donor, with a variable contribution of c

In benzene solution, C60 and C7o interact weakly in the ground state with amines having favourable oxidation potentials. Picosecond time-resolved absorption measurements show that on photoexcilation, the weak complexes undergo charge separation to produce ion pairs which in turn undergo fast geminat
