The fabrication of ultralong titanyl phthalocyanine micron wires by using solution method

One-dimensional ultralong titanyl phthalocyanine sub-micron wires have been synthesized by solution method.The optical micrographs of TiOPc sub-micron wires prepared by different solvents indicated that alcoholic solvents were in favour of getting long TiOPc wires.Meanwhile,change of mass concentration had a great influence on the length of nanowire in the solution.The TiOPc sub-micron wires were determined by atomic force microscope and scanning electron microscope.The results showed that aspect ratio of the wires could reach 100.Organic transistors based on these wires were fabricated and showed typical p-channel characteristics.
