New Organic Molecules with Unusual Properties

本研究计划的主要重点是合成和研究以前未知的环，多环和聚合物有机化合物，其中多个乙炔单元可以通过空间（同共轭）或通过中间杂原子或环丙烷相互电子通信。具体来说，含乙炔的合成目标是第一个磷碳笼分子、第一个硫碳环、三元素笼分子（C、P、S）、硫碳聚合物、4侧和5侧螺环丙基同共轭环聚二炔、单侧只有一个炔单元的5侧螺环丙基同共轭环聚乙炔和一个C(60)H（36）笼分子。这些化合物应该显示出各种不同寻常的电子特性，这些特性将与其他结构特征一起被研究。有了这笔奖金，化学分部的合成有机项目将支持内华达大学里诺分校化学系的劳伦斯·t·斯科特博士的研究。待合成的未知环有机化合物应表现出各种不同寻常的电子性质。在这种精心设计的分子中，对电子离域的结构要求的理解，以及由此产生的后果，应该证明对合理设计能够导电和/或存储电的新型有机材料是有价值的。

The principal focus of this research program is the synthesis and study of previously unknown cyclic, polycyclic and polymeric organic compounds in which multiple acetylenic units can communicate electronically with one another, either through space (homoconjugatively) or via intervening heteroatoms or cyclopropanes. Specifically, the acetylenic-containing synthetic targets are the first phosphocarbon cage molecules, the first thiocarbon rings, tri-element cage molecules (C,P,S), thiocarbon polymers, 4- and 5-sided spirocyclopropyl homoconjugated cyclic polydiynes, the 5-sided spirocyclopropyl homoconjugated cyclic polyacetylene with only one alkyne unit per side and a C(60)H(36) cage molecule. Such compounds should display a variety of unusual electronic properties which will be studied along with other structural features. %%% With this award the Synthetic Organic Program of the Chemistry Division will support the research of Dr. Lawrence T. Scott of the Department of Chemistry at the University of Nevada - Reno. The unknown cyclic organic compounds which will be synthesized should display a variety of unusual electronic properties. An understanding of the structural requirements for electron delocalization in carefully designed molecules of this sort and the consequences thereof should prove valuable in the rational design of new organic materials capable of conducting and/or storing electricity.
