Stabilization of excess electrons in molecular charge pockets on nano-surfaces

In previous work we have demonstrated that concentrated charge pockets can form on molecular surfaces that can act to stabilize excess electrons. The charge pockets that are formed result from the fact that the molecular surfaces have extended OH hydrogen bonding networks on one side of the molecular surface, and hydrogen atoms on the opposite side of the surface. The uneven distribution of the OH groups coupled to the partial positive charge of the hydrogen atoms on the opposite side of the surface create these charge pockets that can attract excess negative charge. Herein we will extend the size of our previously reported molecular surfaces (A. F. Jalbout and L. Adamowicz, Mol. Phys. 19, 3101 (2006)) to examine the stability of the resulting dipole-bound anion states.
