The project is focused on research related through molecular concavity. Specifically, how highly concave molecules can: 1) potentially act as supramolecular protection groups; 2) function as selective catalysts; 3) assemble into water-soluble nano-capsules capable of trapping, storing, and separating hydrocarbon gases; and 4) assemble into nano-capsules capable of controlling photochemical reactions carried out within their interiors, will be studied. The focus of the first two subprograms is on hosts soluble in organic media. The molecules in question are some of the largest and most preorganized ones in the literature. Consequently, a wide range of molecules can be trapped within their concave binding sites. The second two subprograms rely on water-soluble hosts and the hydrophobic effect to drive their assembly into supramolecular capsules.With this award, the Organic and Macromolecular Chemistry Program is supporting the research of Professor Bruce Gibb, of the Department of Chemistry at University of New Orleans. Professor Bruce Gibb and his research group will examine how molecules of highly complex structure can augment important chemical processes or circumnavigate contemporary chemical problems. His research could make chemical synthesis more efficient and more environmentally friendly by allowing reactions that normally require chemical solvents to be carried out in water. In addition, it could also provide a new approach to separate hydrocarbon gases. The latter is important as oil reserves are depleted and hence hydrocarbon gas reserves become more important to the economic wellbeing of the country.

该项目的重点是通过分子凹面相关的研究。 具体而言，高度凹分子可以：1）可能充当超分子保护组； 2）作为选择性催化剂的功能； 3）组装成能够捕获，储存和分离碳氢化合物气体的水溶性纳米胶囊； 4）将研究能够控制其内部内部光化学反应的纳米胶囊。 前两个子程序的重点是在有机培养基中可溶的宿主。 所讨论的分子是文献中一些最大，最前的分子。 因此，可以将广泛的分子捕获在其凹形位点中。 第二个子程序依靠水溶性宿主和疏水效应将其组装推向超分子胶囊。随着该奖项，有机和大分子化学计划正在支持新奥尔良大学化学系Bruce Gibb教授Bruce Gibb的研究。 布鲁斯·吉布（Bruce Gibb）教授及其研究小组将研究高度复杂结构的分子如何增加重要的化学过程或绕过当代化学问题。 他的研究可以通过允许通常需要在水中进行化学溶剂的反应来使化学合成效率更高，更环保。 此外，它还可以提供一种新的方法来分离烃类气体。 后者很重要，因为石油储量被耗尽，因此碳氢化合物储气储量对国家的经济福祉变得越来越重要。
