摘要：

Two new complexes of Ir(I) using diphosphine and diphosphinite calix[4]arene ligands have been prepared and characterized. The luminescent lowest energy excited MLCT state (metal-to-ligand charge transfer) has been addressed theoretically by extended Huckel molecular orbital calculations (EHMO), and a Franck-Condon analysis on the absorption spectra using the time dependent Heller's theory, has been made. The perturbation of tau(e) of the two complexes in ethanol at 77 K by the addition of substrates (UO22+, Li+, Na+), is investigated. The amplitude in tau(e) change with additions of substrates varies as UO22+ > Li+ > Na+.
