This is an abstract for a talk to be given at the Fifth Foresight Conference on Molecular Nanotechnology.
The (100) surface of diamond undergoes spontaneous reconstruction to a surface consisting of C2 "dimers". When the surface is hydrogenated, these dimers are comprised of sp3 carbon, as is the bulk. However, if the hydrogen atoms are not present, either double-bonded alkene moeities (sp2 hybridized carbon) or partially pyramidalized biradical moeities will be formed.
These strained alkenes exhibit hybridization intermediate between sp2
and sp3, and are potential reactive sites for further additions during
mechanosynthesis or CVD. We report the results of ab initio
calculations on a series of strained aklenes and illustrate the
changes in bond order, hybridization, and reactivity by visualizing
the three-dimensional structure of the Laplacian of the electronic
