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.

这一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，在这些化合物中，多个乙炔单元可以通过空间(同位共轭)或通过介入杂原子或环丙烷相互电子通信。具体地说，含乙炔的合成目标是第一个磷碳笼分子，第一个硫碳环，三元笼状分子(C，P，S)，硫代碳聚合物，4-和5-侧螺环丙基高共轭环聚二炔，该5面螺环丙基均共轭环状聚乙炔每侧只有一个炔单元和一个C(60)H(36)笼形分子。这类化合物应该表现出各种不寻常的电子性质，这些性质将与其他结构特征一起进行研究。化学部合成有机计划将支持内华达大学雷诺分校化学系的劳伦斯·T·斯科特博士的研究。将被合成的未知环状有机化合物应该表现出各种不寻常的电子性质。对这种精心设计的分子中电子离域的结构要求及其后果的理解，应该被证明对能够导电和/或储存电的新的有机材料的合理设计是有价值的。
