Abstract

Based on the development of multigram synthesis for optically pure helicenes, a series of studies on chiral aromatic compounds has been conducted. Various helicene derivatives were synthesized, some of which exhibited interesting properties in chiral recognition and chiral catalysis. Then, the study was extended to built-up macromolecules, which are synthetic molecules of several thousands daltons with nanometer sizes obtained by connecting the helicene. Such macromole-cules formed layer structures, controlled bimolecular, and higher aggregate structures by the interactions of the helical π-electron systems. It should be noted that various double-helix molecules were obtained by this method. Gel formation and nanoparticle aggregation were examined using the self-assembly of the built-up macromolecules. This is an example of organic synthesis to challenge the integration of substances from small molecules to large molecular systems.
