Molecular Materials for Lightweight Lasers, and Novel Organic Metals

9812046 wudl这个项目的重点是设计和开发用于轻质有机/无机激光器、半导体和金属的分子。该研究将分三部分进行：(a)基于稳定偶极分子的新材料的制备，(b)薄膜器件的制造和(c)器件特性的确定。新分子和由它们衍生的材料属于一种新型的特殊两性离子类非凯库勒（NK）体系。这些偶极异构体和多（异构体）将被功能化，以修改和改善各种性能，如溶解度，成膜，发光器件，如发光二极管（led）和激光器，以及与材料性能相关的扩展分子间相互作用，包括导电性和铁电性。染料的光物理性质将被评估，固体将使用实验凝聚态物理的最新发展进行检查。除了开发激光器和其他器件（如led）的新材料外，我们的目标是为21世纪培养材料科学家，他们不仅在技术、科学和工程训练方面比普通学生拥有更广泛的技能基础，而且还能培养在研究生院很少获得的辅助才能。这些包括：(a)在跨学科团队中有效地工作以解决问题；(b)第一手了解学术界内外的研究重点、目标和工作方式。拟议的研究通过物理学家、化学家和工程师之间的跨学科互动，自然有助于实现这些目标

9812046WudlThis project focuses on the design and development of molecules for lightweight organic/inorganic lasers, semiconductors, and metals. The research will be carried out in three parts: (a) preparation of new materials based on stable dipolar molecules, (b) fabrication of thin film devices and (c) determination of device characteristics. The new molecules, and materials derived from them, belong to a novel special zwitterionic class of non-Kekule (NK) systems. These dipolar heteroacenes and poly(heteroacenes) will be functionalized to modify and improve various properties such as solubility, film-formation, luminescence for devices such as Light Emitting Diodes (LEDs) and lasers, and extended intermolecular interactions related to materials properties that include conductivity and ferroelectricity. The photophysics of the dyes will be evaluated, and the solids will be examined using the latest developments in experimental condensed matter physics.%%%In addition to developing new materials for lasers and other devices such as LEDs, the goal is to produce materials scientists for the twenty-first century who not only have a much broader skills base than the usual student in terms of their technical scientific and engineering training, but also who develop ancillary talents rarely acquired in graduate school. These include: (a) working effectively in interdisciplinary teams to solve problems and (b) appreciating first-hand the research priorities, objectives, and modus operandi inside and outside of academia. The proposed research lends itself naturally to accomplishing these goals through the interdisciplinary interactions among physicists, chemists and engineers.***
