Abstract

DFT and NMR calculations performed on isophlorin (1) and their derivatives (2–10) show that the 4O and the trans 2O, 2S derivatives (2 and 5) are anti-aromatic. The presence of strong S. . . S pπ-pπ bonding interactions stabilizes the planar structure (5) compared to the non-planar cis-isomer (8). Isophlorins are predicted to have very low electron reorganization energies (λelectron ~ 0.10 eV) which remain unaffected by puckering through steric interactions or solvation in aqueous media. We predict isophlorins to be the ideal candidates for n-Channel organic conductors.
