Solution-processed microwires of phthalocyanine copper(II) derivative with excellent conductivity.

Well-defined 1D microwires of CuPcOC4 with diameters of about 1.0 microm and lengths ranging from 260 to 300 microm as well as ultralong microwires (>5 mm) with diameters of about 10 microm and high length/diameter aspect ratios were synthesized via a simple solution process. Electrical conductive devices based on these microwires fabricated in situ on glass substrates with two ITO electrodes exhibited excellent conductivity properties.
