Polymer single-chain nanoparticles (SCNPs) have found a wide range of applications spanning catalysts, sensors and nanomedicine. The generation of structured SCNPs from star-shaped polymers with diverse architectures and functionalities affords a new avenue to expand the emerging research area. The large-scale synthesis of structured SCNPs is described by the electrostatics-mediated intramolecular crosslinking of three types of 3-armed star-shaped polymers (T-P4VP, T-PS-b-P4VP, and T-P4VP-b-PS), whose configuration is tunable from spherical to cage-shaped to dumbbell-shaped and star-shaped. The structured SCNPs are amphiphilic and can be used as solid surfactants to stabilize different types of emulsions.
聚合物单链纳米颗粒（SCNPs）在催化剂、传感器和纳米医学等领域有着广泛的应用。通过具有不同结构和功能的星形聚合物的静电介导分子内交联，可以得到具有结构的 SCNPs，为扩展新兴研究领域提供了新途径。本文报道了三种 3 臂星形聚合物（T-P4VP、T-PS-b-P4VP 和 T-P4VP-b-PS）的静电介导分子内交联的大规模合成，其构型可从球形到笼形到哑铃形和星形进行调节。具有结构的 SCNPs 具有两亲性，可用作固体表面活性剂来稳定不同类型的乳液。
