| Research Abstract |
We demonstrated in this study that cellulosic block copolymers containing cellulose triacetate or methylcellulose were of academic importance to understand their structure-property relationships. Our synthetic strategy regarding CTA enabled us to align gold nanoparticles by CTA derivatives and to control interparticle distances depending on the length of CTA molecules. Cellulose having pyrene group at the reducing-end self-assembled to form nanoparticles with a single layer of the cellulose derivative. Moreover, we have synthesized diblock methylcellulose derivatives with regioselective functionalization patterns. These derivatives permitted us to find that the diblock structure consisting of cellobiosyl block and approx. ten 2, 3, 6-tri-O-methyl-glucopyranosylunits was of crucial importance for thermoreversible gelationof methylcellulose.
