| Abstract
| - Heteroselenometallic cubane-like clusters (μ3-MoSe4)M3(PPh3)3Cl (M = Cu (I) and Ag (II)) were synthesizedby the reactions of [Et4N]2[MoSe4] and M(PPh3)3Cl in solid state for nonlinear optical studies. Their opticalresponses to the incident light exhibit strong optical limiting effect with thresholds of 1.8 J/cm2 for cluster Iand 0.8 J/cm2 for cluster II in a 0.5 Hz repetition rate condition with nanosecond-duration laser pulses at 532nm. The optical limiting power of II was testified to be an effective broad band optical limiter with the 1064nm wavelength laser pulses from the nanosecond Na:YAG laser. In this respect, cluster II is obviously betterthan cluster I and C60. The nonlinear responses for the two clusters in CH2Cl2 have been studied in a picosecondtime-resolved pump−probe experiment. The heavy atom effect to the efficiency of nonlinear absorption wasalso discussed.
