In recent years, there has been a great deal of interest in the templated synthesis of mesoporous carbons. Most of these attempts have involved carbonization of sugars or various polymeric precursors inside of a mesoporous silica template, followed by removal of the template out from under the carbon skeleton. Functionality obtained by this approach tends to be a random mixture of oxygenated functionalities and is not readily controlled or dictated. We have developed a novel synthetic strategy for building functional mesoporous carbons around specific heteroaromatic functionality, creating a new class of materials that are useful for chemical separations and catalyst supports. Examples of three different synthetic strategies, built around thiophene, pyridine and 1,10-phenanthroline will be presented.
