Abstract
This invention is directed to functionalized higher diamondoids having at least one functional group. Preferably these derivatives have the following Formula I: wherein D is a higher diamondoid nucleus and wherein R, R, R, R, Rand Rare independently selected from a group consisting of hydrogen and functional groups, provided that there is at least one functional group on the derivative. The functionalized higher diamondoid compounds may also be of the formula D—L—(D)wherein D is a higher diamondoid nucleus and L is a linking group and n is 1 or more. The functionalized higher diamondoid compounds additionally may be of the formula R—D—D—Rwherein D is a higher diamondoid nucleus and Rand Rare substituents.
