| Outline of Final Research Achievements |
Development of π-conjugated molecules with a three dimensional (3D) structure have gained increased interests as the charge transporting materials. Metal complexes with π-conjugated ligands are attractive because a wide variety of 3D structures can be constructed, as represented by tris(8-hydroxyquinoline)aluminum (Alq3) for its electron transporting characteristics. We considered that the 3D π-conjugated molecules with enhanced intermolecular π-π interactions in the solid-state can be obtained by an extention of the π-system of the 8-hydroxyquinolinato ligands. In this research, π-extended 8-hydroxyquinolinato ligands were synthesized by using palladium-catalyzed intramolecular direct arylation. We found that the regioselectivity of the intramolecular cyclization can be controlled by the reaction conditions. Then the formation of aluminum complexes were examined and the solid-state structure was revealed by X-ray crystal structure analysis.
