| Outline of Final Research Achievements |
The author has elucidated the mechanism of dynamic glucan-polythiophene hybridization by using curdlan and schizophyllan as representative unbranched and branched linear polysaccharides and polycationic PyPT as a chromophoric hybridization partner. The in situ hybridization to hetero-triplex [(Cur)2-PyPT] upon addition of an aqueous solution of PyPT to a DMSO solution of Cur at ambient temperatures turned out to be far from completion. It should be emphasized that polycationic PyPT can unzip Cur homo-triplex and hybridize with the resulting homo-duplex in neutral aqueous solutions, despite that Cur homo-triplex does not show any sign of disassembling even at high temperatures in the absence of PyPT or in the presence of neutral PT. Interestingly, the hetero-triplex disassembles to hetero-duplex at very high pHs (>11) through further deprotonation from Cur in the hetero-triplex.
