Outline of Final Research Achievements	Construction of molecule-polymer hybrid-type structure, in which semiconducting organic pi-electron skeletons are partially connected with a covalent bond to each other, was achieved to realize the aggregated structures of the organic semiconducting materials possessing a small effective mass. It was actually clarified that such oriented structures show a remarkably small effective masses. In addition, a new process was also developed to fabricate the thin film of the organic semiconducting molecules synthesized in this research. These results should provide an important insight into the molecular design principle and electronic device fabrication process technology.
