A new polymeric Ag(I) complex {[Ag 2 (pbbt) 3 ](NO 3 ) 2 ·0.5H 2 O} n [where pbbt = 1,1′‐(1,3‐propylene)‐bis‐1H‐benzotriazole] was synthesized as a good optical limiter. Single‐crystal X‐ray diffraction determined that the complex assumed a rare, two‐dimensional lamellar structural motif with isolated cavities of [Ag 6 (pbbt) 6 ]. The Z ‐scan measurements of an 8‐ns pulsed laser at 532 nm revealed that the presented complex in dimethylformamide exhibited very strong third‐order optical nonlinear absorption. The optical‐limiting (OL) performance was investigated in the sample of the complex induced by 8‐ns and 30‐ps pulses at 532 nm. The results show that this complex exhibited large OL effects with a very low limiting threshold value of 0.16 J/cm 2 under 8‐ns pulse and 0.56 J/cm 2 under 30‐ps pulses, among those of the best OL materials. Density functional theory calculation results further confirmed the cooperative contributions of Ag ions and bridge ligands to the optical nonlinearities of Ag(I)‐containing metal–organic complex. © 2011 Wiley Periodicals, Inc.
