Polymer reptation for molecular assembly of copper phthalocyanine

An efficient molecular assembly in vacuum and on solid state surface is demonstrated by using copper phthalocyanine (CuPc) as the candidate molecule wherein the assembly is dependent on the coassistance of the reptation of polymer chains and the pi-pi interactions of CuPc. The films assembled by this method exhibit high electronic performance, e. g., the carrier mobility based on the assembled CuPc films is improved by one order compared to that of the devices based on unassembled CuPc films, indicating their prospective application in organic electronics. c 2009 American Institute of Physics.
