    Abstract

    Based on the crystal structure analysis, the overlap integral between the frontier molecular orbitals of adjacent F8CuPcs in the one-dimensional chain is estimated: the overlap integral between the lowest unoccupied molecular orbitals is 5.4 × 10-3, which is larger than that in a typical n-type semiconducing material F16CuPc (2.1 × 10-3), whereas that between the highest occupied molecular orbitals is 2.9 × 10-4. Contrary to previous studies in air, we found that an organic field-effect transistor (OFET) composed of F8CuPc essentially shows clear n-type semiconducting behavior in vacuum.
