Excited states metal centered

The colorless tetramer Ccu(py)l] is fairly stable only in non- or weakly coordination solvents such as benzene, CH Cl, or acetone. At room temperature in solution this copper complex shows an intense red photoluminescence ( 0.04 a f nax = nm (54). The emitting state is a metal-centered 3d 4s excited state which is strongly modified by Cu(I)-Cu(I) interaction in the tetramer. This consists of a (Cul) cubane core. [Pg.165]

It is also necessary to take account of outer sphere contributions to the quenching of the metal-centered excited state. The nature of the outer sphere will vary from one complex to another, depending on the size, charge, and shape of the complex. However, it is possible to correct for a generalized outer sphere contribution for each lanthanide giving a new equation for q which can be expressed in several ways 74... [Pg.924]
