Chiral nanostructures are asymmetric nanoarchitectures that cannot be superimposed with their mirrored-symmetric counterparts, which have attracted considerable attention due to their special photophysical properties and potential applications in plasmonics, spectroscopy and nanosensors. In particular, Self-Assembly of chiral nanostructures with symmetric or asymmetric objects might exhibit exceptional optical activity because those chiral superstructures can manipulate chiral states of light that leads to circular dichroism (CD) effect. This review highlights recent advances on the self-assembly of plasmonic chiral superstructures from simpler dimeric, and trimeric chiral nanoassemblies to complicated chiral nanoarchitectures, especially emphasizes the resulted superior optical activity and the corresponding principles.

具有强烈的手性活动的等离激子手性上层结构的自组装

手性纳米结构是不对称的纳米结构，不能与其镜像对称的对应结构重叠，由于其特殊的光物理性质以及在等离子，光谱学和纳米传感器中的潜在应用，已引起了相当大的关注。特别地，具有对称或不对称物体的手性纳米结构的自组装可能表现出优异的光学活性，因为那些手性超结构可以操纵光的手性态，从而导致圆二色性（CD）效应。这篇综述着重介绍了等离激子手性超结构自组装的最新进展，从简单的二聚体，三聚体手性纳米组装体到复杂的手性纳米体系结构，特别强调了所产生的优异光学活性和相应的原理。
