| 摘 要： | 近年来,超分子组装在催化、制药、传感器、提纯、组织工程等领域获得广泛应用.为了实现超分子结构功能化,经常会将金属纳米颗粒或者金属活性位引入或共组装至有机超分子骨架中,由此获得金属化的纳米材料.例如,金属纳米颗粒修饰的多肽纤维、金属聚合物、金属负载的水凝胶和气凝胶.常见的金属化策略包括自组织、金属有机配位络合、聚合和电子...

| Abstract: | The applications of supramolecular metal-peptide assemblies as catalyst or catalyst precursor have recent attracted increasing attentions. In this work, a fragment of the amyloid β-peptide, NH2-KLVFF-COOH, was assembled into nanofilms with encapsulated Pd, Pt and Au nanoparticles (NPs) via a one-step room temperature electron induction method. The effects of building block, intermolecular interaction, driving force and side-chain on the assembly were investigated. The assembly mechanism was thereby proposed. The crosslinking of peptide monomers results in mainly random and unordered structures. The obtained metal-peptide assemblies are extremely stable in water at neutral pH for long term. However, the metal NPs are able to be responsively released under basic and reductive conditions. The released NPs show a high activity to catalyze the reduction of 4-nitrophenol. The present studies on assembly mechanism and responsive release will be helpful for the design of organic skeletons and also for the future development of peptide stabilized metallic NPs with applications beyond catalysts. |
