The Cyclocarbons: Synthetic All-Carbon Molecules and Precursors to New Carbon Polymers

合成有机项目资助了加州大学洛杉矶分校化学系的Francois N. Diederich博士、Orville L. Chapman博士和Robert L. Whetten博士的合作研究。这个跨学科的项目结合了有机合成和物理化学表征的最先进的方法，以获得对全碳分子和聚合物的结构和键合的新的基本见解。这项研究的目的是探索新的碳同素异形体的化学性质，这些同素异形体不同于由石墨、钻石和朗斯代尔石组成的三种自然修饰。乙炔的三轮车ın !碳（n = 6-72）将通过闪蒸热解/激光加热实验或光解从稳定的、特性良好的前体中制备成可分离的全碳分子。环碳将作为全碳单体，用于控制形成晶体聚合物碳同素异形体，由脱氢环烯的规则网络组成。

The Synthetic Organic Program is funding the collaborative research of Dr. Francois N. Diederich, Dr. Orville L. Chapman and Dr. Robert L. Whetten in the Department of Chemistry at the University of California, Los Angeles. This interdisciplinary program combines state-of-the-art methodology in organic synthesis and in physical chemical characterization to gain new fundamental insights into the structure and bonding of all-carbon molecules and polymers. The goal of the study is to probe the chemistry of new carbon allotropes that differ from the three natural modifications which consist of graphite, diamond and lonsdaleite. Acetylenic cycloın!carbons (n = 6-72) will be prepared as isolable all-carbon molecules from stable, well-characterized precursors by the use of flash pyrolysis/laser heating experiments or by photolysis. The cyclocarbons will serve as all-carbon monomers for the controlled formation of crystalline polymer carbon allotropes, composed of regular networks of dehydroannulenes.
