With funding from the Organic Dynamics Program this project by Professors Gust and Moore of Arizona State University will design, synthesize, and study multicomponent supramolecular species that are molecular triads and pentads consisting of porphyrins, quinones, and carotenoids which perform as light activated switches, OR gates, or NAND gates and other logic elements. Mimicry of biological membranes using fullerenes covalently bonded to carotenoid polyenes and incorporated into liposomes will also be explored. Various structural permutations and combinations of porphyrins, fullerenes, quinones, and carotenoids into supramolecular structures will be studied. This investigation will build complex molecular structures from molecules similar to chlorophyll and beta carotene found in plants to create light harvesting materials with unique properties. Applications of these supramolecular compounds to the transport of energy and in mimicking transistors will be studied.

在有机动力学项目的资助下，亚利桑那州立大学的古斯特和摩尔教授将设计、合成和研究多组分超分子物种，这些超分子物种是由卟啉、醌和类胡萝卜素组成的分子三联体和五联体，它们充当光激活开关、或门或与非门和其他逻辑元件。还将探索利用富勒烯与类胡萝卜素多烯共价键合并结合到脂质体中来模拟生物膜。将研究卟啉、富勒烯、醌和类胡萝卜素到超分子结构的各种结构排列和组合。这项研究将从植物中发现的类似于叶绿素和β胡萝卜素的分子建立复杂的分子结构，以创造具有独特性能的捕光材料。这些超分子化合物在能量传输和模拟晶体管方面的应用将被研究。
