This project targets nanoscale control of molecular assembly to create integrated, functional systems such that "every atom counts", i.e. the active volume and function is maximized relative to the atomic density. The approach makes use of organized interfaces with high surface areas and amplification of response. The research is synthesis and processing focused to determine the molecular synthesis and 3 dimensional organization needed to structurally integrate hierarchical assembly with interacting electro-optic functionalities. Because of the ease of simultaneous synthesis and processing and the huge chemical diversity that is accessible through composition, inorganic modification, organic incorporation, and multidomain assembly, the potential significant technological applications are great. In order to realize these possibilities, it is essential to be able to predictively design and control the multivariable kinetic and thermodynamic parameters that lead to the desired multiscale structure and functional properties. The educational emphasis for undergraduate, graduate and postdoctoral researchers working on this project will include 1) the promotion of professional careers for female students and postdoctoral associates, 2) providing cutting edge collaborative interdisciplinary interactions and resources within the University of California scientific community, 3) personal exposure to leading research and educational programs in world-wide institutions, and 4) provision of summer "hands-on" training opportunities for K-12 and community college students. The goal of this project is to enable, by controlled molecular assembly, the creation of multi-functional devices made up of thin films, coatings or fibers that have thickness' which are the diameter of a human hair or smaller. The thin films, coatings and fibers will contain self-assembled, 3-d patterned and interfaced functional components that are dimensioned on the molecular and nanoscale. Synthesis and processing are carried out simultaneously to greatly reduce the expense and time normally associated with multi-step assembly. Commercial interest includes low-dielectric coatings, optical limiters, photovoltaics, photocatalysts, chemical and bio sensors, displays, microcavity lasers and laser arrays, battery electrolytes, and optical data storage.

该项目的目标是在纳米尺度上控制分子组装，以创建集成的功能系统，这样“每个原子都有价值”，即相对于原子密度，活性体积和功能最大化。该方法利用了具有高表面积和响应放大的有组织界面。研究的重点是合成和加工，以确定分子合成和三维组织需要在结构上整合层次组装与相互作用的电光功能。由于易于同时合成和加工，并且通过组成，无机改性，有机掺入和多域组装可以获得巨大的化学多样性，因此潜在的重大技术应用是巨大的。为了实现这些可能性，必须能够预测设计和控制多变量动力学和热力学参数，从而获得所需的多尺度结构和功能特性。对参与该项目的本科生、研究生和博士后研究人员的教育重点将包括：1)促进女学生和博士后助理的职业发展；2)在加州大学科学界提供前沿的跨学科合作互动和资源；3)个人接触世界各地机构的领先研究和教育项目；4)为K-12和社区大学学生提供暑期“动手”培训机会。该项目的目标是通过控制分子组装，创造出由薄膜、涂层或纤维组成的多功能设备，这些设备的厚度只有人类头发的直径或更小。薄膜、涂层和纤维将包含自组装、三维图案和界面功能组件，这些组件的尺寸在分子和纳米尺度上。合成和加工同时进行，大大减少了通常与多步组装相关的费用和时间。商业利益包括低介电涂层、光学限制器、光伏、光催化剂、化学和生物传感器、显示器、微腔激光器和激光阵列、电池电解质和光学数据存储。参与该项目的本科生、研究生和博士后研究人员的教育重点包括促进女学生和博士后助理的职业生涯，在加州大学科学界提供尖端的跨学科合作互动和资源，个人接触世界各地机构的领先研究和教育项目，并为K-12和社区大学的学生提供暑期“动手”培训机会。
