The monomerization of cis-cisoid cyclobutane dimer of 1,3-dimethylthymine is photosensitized by riboflavin tetraacetate with quantum yields of larger than unity in Ar-purged solution in the presence of perchloric acid, whereas the limiting quantum yi

Methylene-bridged trichromophoric A-D-D′ reveals only triplex emission at longer wavelength than bichromophoric A-D′ and A-D, providing a model for long-range emissive and nonemissive electron transfer between A and D′ through π spacer D.

The isomerization of Hexamethyl(Dewar benzene) to hexamethylbenzene is photosensitized by 1,4-dicyanonaphthalenearene exciplexes. Spectroscopic and quantum-yield studies suggest that the isomerization proceeds mostly through an adiabatic pathway from

Evidence for the intervention of emissive triplexes has been presented for quenching of 1,4-dicyanonaphthalene-arene exciplexes by aromatic olefins. Chemical implications of the triplexes are discussed in relation with reactivities of olefins in geom
