Outline of Final Research Achievements

Precise design of π-electronic ion pairs enabled the fabrication of highly organized dimension-controlled ion-pairing assemblies, including nanoscale specific morphologies, supramolecular gels, liquid crystals, etc. The π-electronic ion pairs were prepared by utilization of the receptor-anion complexes based on anion-responsive π-electronic molecules, and modified “genuine” π-electronic ions. Such π-electronic ion pairs afforded fine-tuned geometries and electronic states, which are suitable for ion-pairing assemblies. Appropriately designed ion-exchange conditions for such π-electronic ion pairs also enabled the fabrication of various π-electronic ion pairs. The π-electronic ion pairs afforded dimension-controlled assemblies as charge-by-charge and charge-segregated modes, exhibiting promising electronic properties such as charge-carrier transport behaviors.
