项目摘要

The scope of the current proposal is to devise new Electron Donor Acceptor Nanocomposites that will lead to significant improvements in energy conversion and transport via the biomimetic organization of electro- and photoactive ensembles electrostatically assembled to carbon nanotubes (CNT). On the basis of available experimental results the proposed nanoscale systems promise to be extremely valuable to solar energy conversion ¿ specifically to novel chemical and light driven systems ¿ and high mechanical strength materials. The basic rationales are the electron acceptor features of CNT. Structural design of new ¿molecular¿ carbon nanostructures, which are soluble in condensed media, emerge as powerful means to control/modify energy conversion and transport. Tuning of the interactions can satisfy a variety of purposes that range from the preparation of electron donor-acceptor nanocomposites to augmented strength materials. The long-term objective is generation and characterization of reactive intermediates following light-induced reactions in order to probe the electron and energy storage properties of CNT in i) homogeneous organic media and ii) thin films at ITO electrodes. The ultimate goal of the integrated project is, through the use of models, to develop relationships between chemical / physical / photophysical properties and the introduction of specific functionalities.

当前提案的范围是设计新的电子供体受体纳米复合材料，通过静电组装到碳纳米管（CNT）上的电活性和光活性整体的仿生组织，显着改善能量转换和传输。根据现有的实验结果，所提出的纳米级系统有望对太阳能转换（特别是新型化学和光驱动系统）以及高机械强度材料极其有价值。基本原理是碳纳米管的电子受体特征。可溶于凝聚介质的新型“分子”碳纳米结构的结构设计成为控制/改变能量转换和传输的有力手段。相互作用的调节可以满足从电子供体-受体纳米复合材料的制备到增强强度材料的各种目的。长期目标是光诱导反应后反应中间体的生成和表征，以探测 i) 均质有机介质和 ii) ITO 电极薄膜中 CNT 的电子和能量存储特性。该集成项目的最终目标是通过使用模型，开发化学/物理/光物理特性之间的关系以及引入特定功能。
