Preparation of Monolayer Films Containing Biomimetic Photovoltaic Molecules and Their Study Using Scanning Probe Techniques

该奖项由化学司特别项目办公室在材料合成和加工倡议下颁发。分子大小的光伏装置将利用自然光合作用的原理来设计和合成。这些器件将被结合到朗缪尔-布洛杰特薄膜和金属表面的自组装单分子膜中，并使用时间分辨光学技术进行研究。生产这种有组织的组件将克服由于电荷的低效分离和跨界面的电荷注入而导致的低电流产额。将开发一种扫描光电化学显微镜探针，能够测量薄膜小区域甚至单个分子的光电响应。基于单层薄膜的材料在制造电子器件，特别是光伏方面具有很大的前景。

This award is made by the Office of Special Projects in the Chemistry Division under the Materials Synthesis and Processing Initiative. Molecule-sized photovoltaic devices will be designed and synthesized using the principles of natural photosynthesis. These devices will be incorporated into Langmuir-Blodgett films and self-assembled monolayers on metal surfaces, and studied using time-resolved optical techniques. Producing such organized assemblies will overcome low current yields due to inefficient separation of electrical charge and injection of charge across interfaces. A scanning photoelectrochemical microscopy probe will be developed, capable of measuring the photoelectrical response of small regions of the films, or even of individual molecules. %%% Materials based on monolayer films hold substantial promise for the fabrication of electronic devices in general and photovoltaics in particular.
