项目摘要
In this project, funded by the Chemical Structure, Dynamics, and Mechanisms B Program of the Division of Chemistry and the Electronic and Photonic Materials Program of the Division of Materials Research, Professor Jacob W. Ciszek of the Department of Chemistry and Biochemistry at Loyola University Chicago is creating novel chemical solutions to processing issues associated with organic semiconductors. Organic semiconductors power modern electronics, for example the organic light emitting diodes in OLED TVs and cell phone displays. This research helps these materials reach their full potential by developing surface chemistry that can addresses flaws at the interface between the semiconductors and applied metal electrodes/contacts. Research also contributes to the fundamental understanding of the surface phenomena which are the important first step in the reactions of all molecular materials. The project also continues the Emerging Scientist Workshop, which immerses high school students in actual experiments performed by the host laboratories, and provides information on a broad spectrum of scientific fields, and advice on scientific careers.Monolayers on classical solid substrates (Alumina, Silicon, Silicon oxide, etc.) were developed decades ago but have not been developed for the new molecular thin films utilized in many modern electronic devices. Accordingly, this project develops monolayers for two molecular surfaces, 2,2ʹ,2ʹʹ-(1,3,5-benzinetriyl)-tris(1-phenyl-1-H-benzimidazole) (TPBi, a benchmark OLED material) and pentacene (the organic field effect transistor benchmark) via vapor dosing of the reactants onto the solid surface. Chemical challenges include molecular orientation within the substrate which dictates reactivity and surface defect nucleation of reactivity generating non-uniform coverages. Upon successful development of reaction, molecular series are utilized to eliminate metal penetration issues for top contacts deposited onto TPBi, while reactions on pentacene are utilized to increase conductivity in devices. In the latter, the molecular series is designed to elucidate the mechanism behind increased conductance.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
本计画由化学系化学结构、动力学与机制B计画及材料研究系电子与光子材料计画所资助,芝加哥洛约拉大学化学和生物化学系的Ciszek正在创造新的化学解决方案,以解决与有机半导体相关的处理问题。 有机半导体为现代电子产品提供动力,例如OLED电视和手机显示器中的有机发光二极管。 这项研究通过开发表面化学来帮助这些材料发挥其全部潜力,这些表面化学可以解决半导体和应用金属电极/触点之间界面的缺陷。 研究还有助于对表面现象的基本理解,这是所有分子材料反应的重要第一步。 该项目还继续举办新兴科学家讲习班,让高中生沉浸在主办实验室进行的实际实验中,并提供有关广泛科学领域的信息和科学职业的建议。传统固体基底(氧化铝、硅、氧化硅等)上的单层膜几十年前就已经开发出来了,但是还没有开发出用于许多现代电子器件中的新分子薄膜。 因此,该项目开发了两种分子表面的单分子层,2,2-二甲基-2-(1,3,5-benzinetriyl)-三(1-苯基-1-H-苯并咪唑)(TPBi,一种基准OLED材料)和并五苯(有机场效应晶体管基准),通过将反应物蒸气定量给料到固体表面上。 化学挑战包括基材内的分子取向,这决定了反应性和反应性的表面缺陷成核,从而产生不均匀的覆盖。 在反应成功发展后,利用分子系列来消除沉积到TPBi上的顶部接触的金属渗透问题,而利用并五苯上的反应来增加器件中的导电性。 该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
