    • Spartan06 (Wavefunction, Inc.) was used for the calculation. A Monte Carlo conformation search was performed by using the MMFF force field to find the lowest-energy conformation, which was then used as an initial structure for the ab initio geometry optimization (RHF/6-31G ). The electrostatic potential map was calculated at the same level of theory.
