摘要：

A new class of long-lived luminescent complexes of the type cis-Re-I(CO)(2)(N-N)(P-P)(+) (where N-N is a chelate polypyridine ligand and P-P is a chelate phosphine) has been prepared. The new Re excited states are of extraordinary stability and exhibit redshifted spectral responses relative to the well-studied fac-Re(bpy)(CO)(3)L(+70) series (L is a variety of neutral and anionic ligands). Of primary interest are their extremely long lifetimes in CH2Cl2 solution, which could be a consequence of an energy gap law different from that of the tricarbonyl complexes.
