项目摘要

This project initiates a collaborative effort between the Federal University of ABC (UFABC), Santo Andre, Brazil and the University of Missouri, Columbia, USA, in the area of peptide nanostructures as active materials and molecular templates for organic electronics. The collaborator from Brazil is an expert in the area of supramolecular chemistry, in particular, in the synthesis of peptide and other bio-inspired functionalized nanostructures. The US investigator is experienced in the area of fundamental optical and electrical studies of organic/polymeric semiconductors. This international collaboration between scientists having complementary expertise aims at the synthesis of new functionalized peptide-based nanostructures (PNS) with conducting polymers (CP) such as poly(3-hexylthiophene) (P3HT). These nanostructures may be utilized in electronic devices such as field-effect transistors (FETs) to probe the interface properties of peptide-based semiconductor/insulator (dielectric) films. By combining optical spectroscopy with charge transport measurements, the nature of charge transport including piezoelectric effects in PNS-CP based FETs will be explored. This collaborative work could be a stepping stone for expanding the research effort into large-area bio-inspired nanotechnology. The project will provide opportunities for educational and outreach activities. A graduate student will work with graduate students from Brazil, enhancing mobility and transferability of skills. The project will also be integrated with existing community outreach activities at the University of Missouri that involve innovative teaching and public policy initiatives.

该项目在美国哥伦比亚州哥伦比亚大学的圣安德烈（Santo Andre）和密苏里大学（UFABC）联邦ABC大学（UFABC）（UFABC）（UFABC）与有机电子学的活性材料和分子模板之间进行了合作。来自巴西的合作者是超分子化学领域的专家，特别是在肽和其他生物启发的纳米结构的合成中。美国研究者在有机/聚合半导体的基本光学和电气研究领域经验丰富。具有互补专业知识的科学家之间的这种国际合作旨在综合新的基于功能化肽的纳米结构（PNS）与导电聚合物（CP）（例如poly（3-己基噻吩））（P3HT）（P3HT）。这些纳米结构可用于电子设备，例如现场效应晶体管（FET），以探测基于肽的半导体/绝缘子（介电）膜的界面特性。通过将光谱与电荷传输测量相结合，将探索电荷传输的性质，包括基于PNS-CP的FET中的压电效应。这项协作工作可能是将研究工作扩展到大区域生物启发的纳米技术的垫脚石。该项目将为教育和外展活动提供机会。一名研究生将与来自巴西的研究生合作，提高移动性和技能的可转移性。该项目还将与密苏里大学的现有社区外展活动集成，该活动涉及创新的教学和公共政策计划。
