摘要： Polymeric carbon can be formed by a method comprising the steps of(a) polymerizing 1-bromo-4-lithiobenzene to form a brominated polyphenylene wherein the ratio of brominated to non-brominated residues in the polymer is 1:5 or greater;(b) functionalizing the brominated polyphenylene to replace the bromide groups with a substituted or unsubstituted acetylene group; and(c) heating the functionalized polymer to a temperature of 900.degree. C. to form polymeric carbon. Preferably, the brominated polyphenylene is formed in an ethereal solvent such as tetrahydrofuran and then functionalized using a palladium catalyst and a copper catalyst. When the acetylene substituent is phenylacetylene, the product of the method is glassy carbon.

摘要翻译： 聚合碳可以通过包括以下步骤的方法形成：（a）聚合1-溴-4-锂苯以形成溴化聚亚苯基，其中聚合物中溴化与非溴化残基的比例为1:5或更大; （b）用取代或未取代的乙炔官能化溴代聚亚苯取代溴基; 和（c）将官能化聚合物加热到900℃的温度以形成聚合碳。 溴代聚亚苯基优选在醚溶剂如四氢呋喃中形​​成，然后使用钯催化剂和铜催化剂进行官能化。 当乙炔取代基是苯基乙炔时，该方法的产物是玻璃碳。
