“…However, as the l xz(yz),# sets to zero (zero constraint field), the system cannot remain in a stationary solution. Also, for 4 A 1g state, no stationary solution is obtained at zero constraint field. Thus, the ground state may be concluded to the 4 E g state.…”

Magnetism and multiplets for metal-phthalocyanine (MPc) molecules with transition-metals (M) of Mn and Co were investigated based on the constraint density functional theory calculations by imposing density matrix constraint on the d-orbital occupation numbers. For the MnPc, the ground state is found to be the 4 E g state with the perpendicular magnetic anisotropy with respect to the molecular plane, while for the CoPc, the ground state is the 2 A 1g state with a planar magnetic anisotropy.

“…[1][2][3][4][5] Moreover, a challenge to miniaturize devices for novel magnetic applications now extends to treating an extreme limit of the single molecule. Importantly, the property of the MPc is governed by the electronic structure, so-called multiplet, which arises from the d-orbitals localized at the transition-metal atom.…”

We report the observation of ambipolar transport in field-effect transistors fabricated on single crystals of copper-and iron-phthalocyanine, using gold as a high work-function metal for the fabrication of source and drain electrodes. In these devices, the room-temperature mobility of holes reaches 0.3 cm 2 / V s in both materials. The highest mobility for electrons is observed for iron-phthalocyanines and is approximately one order of magnitude lower. Our measurements indicate that these values are limited by extrinsic contact effects due to the transistor fabrication and suggest that considerably higher values for the electron and hole mobility can be achieved in these materials.
