The performance of ab initio calculations for the ground and excited states of the Pt(saloph) complex is examined in detail. The SO-Si and T-1-T-i absorption spectra are calculated, and the transition between the ground S-0 state and the excited S-1 state involves the HOMO-2, HOMO-1, HOMO and LUMO. Moreover, calculations show that the emissive singlet is of mixed MLCT/LLCT characteristic. On the other hand, the molecular geometry of the complex is nearly planar in the ground state while the geometry is obviously nonplanar in the excited state of S-1(pi, pi*) in the gas phase.
