This award is made in the Organic Dynamics Program in support of the continuing research of Dr. David Whitten at the University of Rochester. The research will deal with the design, synthesis, and characterization of Langmuir-Blodgett films, vesicles, and membranes bearing aggregates of chromophores. The chromophores will typically be trans-stilbenes, trans-azobenzenes, polypyridines and polypyrimidenes attached to phospholipids, calixarenes or dendrimeric amphiphiles. The research will investigate the the effect of light on the chromophoric aggregates and what influence it has on the stability and physical properties of the films. The ultimate application of these materials will be photoregulatable or optical films and membranes which can change their permeability, stability, and ion-binding ability in a controlled manner upon exposure to light. The synthesis of optical films and membranes whose stability and physical properties can be predictably controlled by light of the appropriate frequency and intensity is of great interest to the organic dynamics, materials and biophysics communities. Such materials are likely to find applications in molecular optoelectronics, drug-delivery systems and gas separation systems.

该奖项是在有机动力学计划，以支持 罗切斯特大学的大卫·惠顿博士继续研究。 本研究将涉及设计，合成和表征 的Langmuir-Blodgett膜，囊泡和膜承载的聚集体， 发色团发色团通常是反式芪， 反式偶氮苯、聚吡啶和聚嘧啶， 磷脂、杯芳烃或树枝状两亲物。 这项研究将 研究光对发色团聚集体的影响， 它对稳定性和物理性能的影响 薄膜.这些材料的最终应用将是 可光调节或光学薄膜和膜， 渗透性、稳定性和离子结合能力 在暴露于光下时。 光学薄膜和膜的合成， 性能可以通过适当的光来可预测地控制， 频率和强度是有机动力学非常感兴趣的， 材料和生物物理学社区。这些材料很可能会发现 在分子光电子学、药物输送系统和气体中的应用 分离系统。
