The focus of this research is the synthesis and origins of the porphyrins from oil shales and petroleum, including porphyrins with five- and six-membered exocyclic rings. In addition, the preparation of N-15 and deuterium labeled porphyrins needed for resonance Raman studies will be carried out. Other porphyrin systems that will be synthesized include porphyrin dimers and novel porphyrin-containing chromophores such as indenoporphyrins, naphth 2,3-b porphyrins, tetranapthoporphyrins, phenanthropor-phyrins, coronenoporphyrins and phenanthrolinoporhyrins. These latter porphyrins will be of particular interest because of their ability to bind metal cations at the external phenanthroline subunit as well as within the central porphyrin cavity. With this award, the Synthetic Organic Program is supporting the research of Dr. Timothy D. Lash of the Department of Chemistry at the Illinois State University. Professor Lash will focus his work on the synthesis of sedimentary cycloalkanoporphyrins, which are geochemical markers that help determine the origins of oil shales and petroleum, and also novel porphyrin-containing chromophores with highly conjugated systems. These later compounds will provide an important new entry into supramolecular porphyrin chemistry.

本论文的研究重点是油页岩和石油中卟啉化合物的合成和起源，包括含五元和六元外环的卟啉化合物。 此外，还将进行共振拉曼研究所需的N-15和氘标记卟啉的制备。 将合成的其它卟啉体系包括卟啉二聚体和新的含卟啉的发色团，例如茚卟啉、萘2，3-B卟啉、四萘卟啉、菲并卟啉、冠卟啉和菲咯啉卟啉。 这些后者卟啉将是特别感兴趣的，因为它们的能力，以结合金属阳离子在外部菲咯啉亚基，以及在中央卟啉腔。 有了这个奖项，合成有机计划是支持博士蒂莫西D。 伊利诺斯州州立大学化学系的莱什说。 Lash教授将专注于沉积环烷卟啉的合成，这是有助于确定油页岩和石油起源的地球化学标志物，也是具有高度共轭系统的新型含卟啉发色团。 这些新化合物将为超分子卟啉化学提供一个重要的新入口。
