Polymorphs of vanadyl-phthalocyanine (VOPc) films were realized on the polymer-modified substrates. Balanced ambipolar transport was observed in the Phase II of VOPc film on the PMMA modified substrate, while only electron transport was obtained on PVA layer. The different transport behavior is believed to be original from their crystalline structures, which may lead to their different energy-band structures. (C) 2014 Elsevier B.V. All rights reserved.
