Professor Cláudio N. Verani at the Wayne State University is supported by the Macromolecular, Supramolecular and Nanochemistry program of the Division of Chemistry to conduct research on the use of metal-containing amphiphiles for redox-active supramolecular thin films. This interdisciplinary program seeks to merge redox-driven switching in transition-metal coordination complexes with molecular organization at surfaces, and focuses on three aims: (i) the development of redox-active amphiphiles and hydrophobes based on five-coordinate M(III)-complexes with electroactive ligands, (ii) the design of redox-active amphiphiles of discoid topology based on modular multimetallic cores, and (iii) the development of novel approaches to assemble extended modular Langmuir films at the air-water interface. These aims require a comprehensive and multidisciplinary knowledge in synthetic methodologies, electrochemical, spectroscopic, computational, isothermal compression, and microscopy methods. This research is an effort to translate information learned from small transition metal complexes into useful systems that foster the development of new materials and devices. The educational component is based on a socio-cognitive approach and uses unifying topics such as soaps and simpler experiments to reach out for graduate students, middle school students, as well as kindergartners of the Detroit School System. In addition, this research provides multidisciplinary research training for undergraduates and graduate students in inorganic and materials chemistry.

克劳迪奥·N.教授Verani在韦恩州立大学得到化学系大分子、超分子和纳米化学项目的支持，对含金属的两亲物用于氧化还原活性超分子薄膜进行研究。这个跨学科的计划旨在将氧化还原驱动的过渡金属配位络合物转换与表面的分子组织合并，并专注于三个目标：（i）基于具有电活性配体的五配位M（III）-络合物的氧化还原活性两亲物和疏水物的开发，（ii）基于模块化多金属核的盘状拓扑的氧化还原活性两亲物的设计，以及（iii）开发在空气-水界面组装扩展模块化朗缪尔膜的新方法。这些目标需要在合成方法，电化学，光谱，计算，等温压缩和显微镜方法的全面和多学科的知识。 这项研究旨在将从小型过渡金属络合物中获得的信息转化为有用的系统，以促进新材料和设备的开发。教育部分是基于社会认知的方法，并使用统一的主题，如肥皂和简单的实验，以达到研究生，中学生，以及底特律学校系统的初学者。此外，本研究为无机和材料化学的本科生和研究生提供了多学科的研究培训。
