Molecular Materials for Lightweight Lasers, and Novel Organic Metals

9812046Wudl该项目专注于设计和开发用于轻型有机/无机激光器、半导体和金属的分子。这项研究将分三个部分进行：(A)基于稳定偶极分子的新材料的制备，(B)薄膜器件的制备和(C)器件特性的测定。这些新的分子及其衍生材料属于一类新的特殊的两性离子非凯库勒(NK)体系。这些偶极杂苯和聚杂苯将被功能化，以修饰和改善各种性能，如溶解性、成膜性、发光二极管(LED)和激光器等器件的发光，以及与材料属性(包括导电性和铁电性)相关的延长的分子间相互作用。将评估染料的光物理，并使用实验凝聚态物理的最新发展来检测固体。%除了为激光和其他设备(如LED)开发新材料外，我们的目标是为21世纪培养材料科学家，他们不仅在技术、科学和工程培训方面比普通学生拥有更广泛的技能基础，而且还培养在研究生院难得获得的辅助人才。这包括：(A)在跨学科团队中有效地合作解决问题；(B)第一手了解学术界内外的研究重点、目标和运作方式。这项拟议的研究自然有助于通过物理学家、化学家和工程师之间的跨学科互动来实现这些目标。

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.***
