Investigation and Exploitation of Anisotropy in Various Molecular Aggregates

这项来自有机动力学项目的续期拨款支持了乔治城大学韦斯教授的研究。这项旨在开发新材料的研究重点是将客体分子的分子结构与液晶、聚合物薄膜、凝胶、膜、沸石和纳米级圆柱体中的反应动力学联系起来。研究的四个重点是：2-萘酰基酯的光化学研究、4-烷基-n -（4-氰苯）-哌啶结晶的动态发射研究、有机液体的ALS凝胶研究和用于手性分离的柱状液晶聚合研究。在这个以材料为导向的项目中，Weiss博士将研究客体分子在受限的复杂介质中的结构和反应动力学，如液晶、聚合物薄膜、凝胶、膜、沸石和纳米级圆柱体。这项多方面的研究采用光化学、量热、光谱和聚合物技术来揭示影响其分子结构和反应性的因素。更好地理解控制这些有组织的分子组装转化的因素将从这项研究中产生，预计将导致具有特定诊断应用的新材料。

This renewal grant from the Organic Dynamics Program supports the studies of Professor Weiss at Georgetown University. The research, which is aimed at developing new materials, focuses on correlating the molecular structures of guest molecules with reaction dynamics in liquid crystals, polymer films, gels, membranes, zeolites, and nanoscale cylinders. The four focal points of research are photochemical studies on 2-naphthyl acylates, dynamic emission studies on crystalline 4-alkyl-N-(4-cyanophenyl)-piperidines, studies on ALS (Aromatics Linked to Steroidal groups) gelators of organic liquids, and studies on polymerizations of columnar liquid crystals for chiral separations. In this materials-driven project, Dr. Weiss will study structures and reaction dynamics of guest molecules in constrained, complex media such as liquid crystals, polymer films, gels, membranes, zeolites, and nanoscale cylinders. This multi-faceted research employs photochemical, calorimetric, spectroscopic, and polymeric techniques to unravel factors that influence their molecular structures and reactivities. A better understanding of the factors controlling transformations in these organized molecular assemblies will result from this research that is expected to lead to new materials with specific diagnostic applications.
