Nanowire-array films of copper hexadecafluorophthalocyanine (F16CuPc) fabricated by templated growth

Abstract

Nanowire-array films of the molecular semiconductor, copper hexadecafluorophthalocyanine (F₁₆CuPc), have been fabricated by templated growth on a pre-deposited planar perylene-3,4,9,10-tetracarboxylic-3,4,9,10-dianhydride (PTCDA) layer. The PTCDA template induces the F₁₆CuPc molecules to adopt a new type of lying-down arrangement with the molecular plane oriented parallel to the substrate instead of the conventional standing-up configuration which occurs on weakly interacting substrates. The resulting nanowire-array films exhibit a structure and morphology that has significant potential for application in a wide range of organic electronic devices.
