用可逆加成锻炼链转移(RAFT)聚合方法合成了两亲性聚(N-苯基马来酰亚胺)-b-聚(4-乙烯基吡啶)-Cd2(PNPV-Cd2)高分子配合物.Cd2离子与4VP基团配位并与硫代乙酰胺分解产生的S2-离子原位生成CdS纳米粒子.聚(N-苯基马来酰亚胺)-b-聚(4-乙烯基吡啶)- CdS( PNPVCdS)中CdS的含量可通过RAFT聚合时间进行调控.用紫外吸收和荧光光谱(PL)测试了PNPV-CdS的光学性质.PNPV-CdS的PL性质可通过RAFT方法进行控制.用Z-扫描的方法在532 nm波长下研究了PNPV-CdS的三阶非线性光学(NLO)性质.PNPV-CdS的NLO响应分别强于CdS和PNPV.这种纳米复合材料在光学信息处理中的全光开关领域具有潜在的应用价值.
The amphipathic poly ( N-phenylmaleimide ) -b-poly ( 4-vinylpyridine ) -Cd2 + ( PNPV-Cd2 + )complex has been synthesized by reversible addition fragmentation chain transfer (RAFT) polymerization.The 4VP groups acted as the coordination sites for cadmium ion aggregations and nanosized CdS particles were successfully grown in situ at these sites with the release of S2- ions from thioacetamide.The CdS content and size in poly(N-phenylmaleimide) -b-poly(4-vinylpyridine) -CdS (PNPV-CdS) nanocomposites were controlled by the polymerization time.The optical properties of the prepared PNPV-CdS nanocomposites were characterized by linear absorption and photoluminescence (PL) spectra.The PL properties of the nanocomposites are controllable by RAFT method.Z-scan measurement was also employed to investigate the third-order nonlinear optical (NLO) properties at a wavelength of 532 nm.The nonlinear optical response of PNPV-CdS is much stronger than that of CdS and PNPV.This nanocomposite has potential applications in all-optical switches in optical information processing.
