Abstract
[Ir(ppy)2(RCOCR’COR)] and [Pt(ppy)(RCOCHCOR)] (ppy= cyclometallated 2-phenylpyridine; R = Me, Ph; R’ = H, 2,4-dinitrophenyl) complexes show an unexpected large second order non linear optical response, as evidenced by the EFISH technique, which can be attributed by an SOS-TDDFT investigation mainly to intraligand charge transfer transitions involving the cyclometallated ligands.
