Distinct Hole and Electron Transport Anisotropy in Ambipolar Nickel Dithiolene-Based Semiconductor.

ABSTRACT: Understanding anisotropic charge transport in molecular semiconductors is crucial for device optimization, yet its intricate dependence on orbital-specific intermolecular interactions and molecular packing remains a challenge, especially in ambipolar systems. In ambipolar semiconductors, where both holes and electrons participate in conduction, distinct molecular orbitals prompt a critical inquiry: can orbital variations result in coexisting yet distinct anisotropic transport properties within a single component? We confirm this possibility by demonstrating that the air-stable nickel dithiolene, Ni(4OPr), exhibits such behavior. Despite its herringbone stacking implying a two-dimensional electronic structure, Ni(4OPr) uniquely exhibits distinct intermolecular interactions for hole (HOMO-to
