| Outline of Final Research Achievements |
It is generally considered that the chemical structures of the junction points of brunched polymers do not largely impact on their properties, because the contribution of a junction point is small with respect to the whole polymer length and gravity. However, we recently found that three-arm star-shaped polymers with a junction point consisting of a tripodal triptycene exhibit significantly different properties from those of three-arm star-shaped polymers with other junction points. In this study, we investigated the remarkable assembling behavior and rheological properties of the triptycene-containing star-shaped polymers.
