摘要: Abstract A novel thiosemicarbazide ligand L and its dinuclear complexes M2(dppm)2L(NO3)2 [where dppm = bis(diphenylphosphino)methane, M = Cu(I) (1), Ag(I) (2)] were designed, synthesized characterized by 1H NMR spectroscopy, elemental analysis, IR, MALDI-TOF mass single crystal X-ray diffraction analysis. The third-order nonlinear optical (NLO) properties of the metal determined open/close aperture Z-scan technique. results reveal that possess much larger susceptibility two-photon absorption cross sections than free in near IR region, especially for complex 2. photophysical them investigated interpreted on basis theoretical calculations (TD-DFT).
