The research objective of this award is to develop facile methods to allow conjugated organic molecules forming a highly organized nanolayer structure. Three main tasks will be performed: 1) rationally design a head-tail structure for a conjugated molecule: the head operates as a critical component for charge conduction and the tail as an active component for layered linkage; 2) investigate the layered formation process and optimize the packing of the ordered structures: the organization depends upon many factors, such as chemical design of the head-tail structure, conformational changes after organization, and a quantified assessment of the interactions between these molecules; and 3) model the molecular packing, revealing size effect or functional group effect to a desired structure.The ability to design, synthesize and model molecules and allow them to form rarely observed nanolayers will add significantly to the body of knowledge regarding to material design/surface engineering. If successful, the ordered film is expected to possess superior electronic properties unachievable in bulk materials. As a result, this work is expected to be of general interest to research laboratories and high-tech industries working on biological thin films, organic electronics, large-area flexible displays, mobile devices, and high-speed sensors. Graduate and undergraduate engineering students and high school teachers will benefit through classroom instruction and summer research involvement.

该奖项的研究目标是开发简便的方法，使共轭有机分子形成高度组织的纳米层结构。 主要完成三项任务：1）合理设计共轭分子的头尾结构：头部作为电荷传导的关键部件，尾部作为层状连接的活性部件； 2）研究分层形成过程并优化有序结构的堆积：组织取决于许多因素，例如头尾结构的化学设计、组织后的构象变化以及这些分子之间相互作用的量化评估； 3）对分子堆积进行建模，揭示所需结构的尺寸效应或官能团效应。设计、合成和建模分子并允许它们形成很少观察到的纳米层的能力将显着增加有关材料设计/的知识体系表面工程。 如果成功，订购的薄膜预计将具有散装材料无法实现的优异电子性能。 因此，这项工作预计将引起从事生物薄膜、有机电子、大面积柔性显示器、移动设备和高速传感器研究实验室和高科技行业的普遍兴趣。 工程专业的研究生和本科生以及高中教师将通过课堂教学和暑期研究参与受益。
