Abstract: Technological advancement relies on the building of faster, more efficient, and smaller machine components. Silicon-based microelectronics have reached the lower limit of their dimension and new materials must be found if the miniaturization trend is to continue. Molecular electronic nanotechnology is the design, synthesis, and study of molecular devices that function analogous to current solid-state electronic devices. This area of study harnesses the characteristics of individual molecules in the design of novel devices. The electron-deficient, distorted square bipyramidal, ten-vertex 1,10-dicarba-closo-decaborane (10), HC(BH)8CH carborane molecules possess characteristics that favor their investigation as molecular electronic components. These boron-based polyhedra are easily functionalized at the terminal carbon atoms possessing a partial positive charge. This charge is due to the presence of the three-centered, two electron bonds that are characteristic of these molecules. With an electronic structure compatible with -molecules, these thermally stable rigid molecules are candidates for use in molecular electronic systems. Five new ten-vertex carborane-based molecules have been synthesized, with two having the capacity for further functionalization. Each was characterized through the use of 1H, 13C, and 11B NMR spectroscopies, as well as infrared, UV-visible and mass spectroscopies, and elemental analysis. We plan to incorporate these insulating bridging molecules (I) in a classical charge-transfer paradigm by bonding them between electron donating (D) and electron accepting (A) structures in a classic D-I-A arrangement. Thus positioned, these molecules may function as 'insulators' in molecular field effect devices.
