摘要
多金属氧簇(Polyoxometalates,POMs)是一类成分和结构具有多样性的单分散纳米团簇.作为新兴的有机无机功能材料,多金属氧簇-嵌段高分子杂化材料在催化、光电化学以及生物化学等领域展现出了良好的应用前景.在此,我们提出了一种简单而新颖的多组分共组装策略,即通过静电相互作用将两亲性嵌段共聚物PEO-PS与Keggin型多金属氧簇H4SiW进行结合,在选择性溶液中制备多金属氧簇-嵌段高分子杂化胶束.利用核磁(1H NMR)、红外(FI-TR)、凝胶渗透色谱(GPC)等测试手段对PEO-PS/H4SiW杂化胶束的结构进行了表征,并通过透射电子显微镜(TEM)对其共组装行为进行了研究.
Abstract
Poly oxometalates(POMs)are monodisperse nanoclusters with diverse composition and structure.As a new organic and inorganic functional material,polyoxometalates-block copolymer hybrid materials have shown a good application prospect in catalysis,photoelectric chemistry and biochemistry.Here,we propose a simple and novel multi-component co-assembly strategy that combines amphiphilic block copolymer PEO-PS with Keggin-type polyoxomethanate H4SiW through electrostatic interaction.The structures of PEO-PS/H4SiW hybrids were characterized by 1 H NMR,FI-TR and GPC,and their co-assembly behavior was studied by TEM.
