摘要

1.Introduction Much interest has been aroused to search for new materials with third-order nonlinear optical (NLO) properties. The potential applications in such materials are optical communication, optical signal processing and transmission, optical data acquisition and storage, optical computing, opticalectronic modulation, and especially optical limiting (OL) effects utilized in the protection of optical sensors and human eyes from high-intensity laser beams. In the past two decades, nonlinear optical research has been mainly focused on inorganic semiconductors, organic molecules, conjugated polymers and organometallic compounds[1]. Only very recently, Mo(W)-S-Ag clusters have been developed as a new promising class of nonlinear optical materials, and gradually attracted much attention due to their possessing the combined advantages of both organic molecules and inorganic semiconductors: large modifiable structures and structures containing many heavy metal atoms [2]. Here we design an effective method to synthesize the first polymeric Mo-S-Ag cluster [Ce(DMSO)8M3Ag3S12]n (1) with helical-chain framework and its isomorphous cluster [Ce(DMSO)8W3Ag3S12]n (2) as third-order nonlinear optical materials.
