Facile fabrication and excellent electrical conductivity of ultralong nanobelt film of butoxy-substituted copper phthalocyanines

Abstract

Well-defined single-crystalline nanobelts of butoxy-substituted copper phthalocyanine (CuPcOC₄) have been rapidly prepared by a facile and reliable non-solvent nucleation method without any template. Remarkably, the nanobelt film exhibited an excellent electrical conductivity of up to 5.2 S m⁻¹, which is one of the highest values reported for organic semiconducting materials.
