Self-Assembly and Collective Properties of Resorcinarene-encapsulated Nanoparticles

普渡大学的Alexander Wei教授得到了分析和表面化学项目的支持，研究金、银和钴的间苯二甲酸乙酯封装纳米颗粒。PI正在开发间苯二甲酸二烯作为大环表面活性剂，以增强金属纳米颗粒的分散和自组装，使其成为具有可调物理性能的材料。这个想法是使用表面配体来附着在特定的粒子面（100）或（111）上，当粒子被压缩成二维阵列或三维超晶格时，这将导致特定的可预测的晶格结构。由纳米颗粒组成的阵列或所谓的纳米晶体可以用于各种新的应用。例如，具有可调谐等离子共振的激光器可用于化学传感。手性磁性纳米畴可用作非易失性数据存储元件。除了在国家安全和计算机等领域的广泛影响外，该项目还将涉及普渡大学新成立的Birck纳米技术中心的学生，该中心结合了包括教育和外展在内的许多活动。

Professor Alexander Wei of Purdue University is supported by the Analytical and Surface Chemistry Program to study resorcinarene-encapsulated nanoparticles of gold, silver and cobalt. The PI is developing resorcinarene as a macrocyclic surfactant to enhance the dispersion and self-assembly of metal nanoparticles into materials with tunable physical properties. The idea is to use surface ligands designed to attach to particular particle faces (100) or (111) that will lead to specific predictable lattice structures when the particles are compressed into a 2D array or 3D superlattice. Arrays or so-called nanocrystals composed of nanoparticles can be developed for a variety of new applications. For example, ones that have tunable plasmonic resonances can be used for chemical sensing. Chiral magnetic nanodomains can be used as nonvolatile data storage elements. In addition to the broader impacts of the work in areas such as national security and computing, the project will involve students in the newly established Birck Nanotechnology Center at Purdue, which combines a number of activities including education and outreach.
