| Outline of Final Research Achievements |
In this study, we have synthesized π-extended helical compounds and investigated their characteristic molecular functions derived from their chiral molecular structure.
The homogeneously π-extended helicenes, that is the helical analog of hexabenzocoronene, tend to have small HOMO-LUMO gap that is significantly decreases with increasing the helical length of the π-extended helicenes. We have also succeeded in the synthesis of π-expanded helical compounds with large helical diameter, which behave as a soft molecular spring with a small molecular spring constant that is ca. one-tenth of that of conventional helicenes.
