Uniaxially oriented, highly ordered, large area columnar superstructures of discotic supramolecules using magnetic field and surface interactions

Uniaxially oriented and highly ordered columnar superstructure of cobalt octa-(n-decylthio)porphyrazine (CoS10) on a large area of substrate has been fabricated, simultaneously utilizing an applied magnetic field and the interaction of CoS10 with an OTS-functionalized substrate. This very simple and straightforward alignment technique can be instrumental for practical applications of discotic supramolecular systems including various organoelectronic devices.
