Inside Cover: Precisely Assembled Cyclic Gold Nanoparticle Frames by 2D Polymer Single‐Crystal Templating (Angew. Chem. Int. Ed. 44/2017)

Abstract

Free-standing frames can be prepared by a directed assembly method in which nanoparticles are precisely linked together by using polymer single crystals (PSCs) as a template. In their Communication on page 13645 ff., C. Y. Li and co-workers use preformed PSCs to direct the crystallization of block copolymers, which in turn direct gold NPs (AuNPs) to form precisely controlled AuNP frames. These AuNP frames topologically resemble nanoparticle rings and cyclic polymer chains, and show unique surface plasmon resonance behaviors.
