| Summary: | 碩士 === 國立中山大學 === 材料與光電科學學系研究所 === 106 === Supramolecular chemistry is a powerful strategy for molecular design due to simple molecular recognition, self-assembly behaviors, a relatively low cost to develop new features of the material. In this study, we prepared the carbazole as the main structure, and polymerized conjugated polymer at 3,6 position, the other is PS-derivatives. After post-functionalization with CuAAC “click” reaction, nucleobase-contained polymers PTC-T、PVBA、PS-b-PVBA and PS-b-PVBT. The supramolecular complexes through Hetero-complementary hydrogen bonding between Adenine and Thymine were investigated. FT-IR, 1H NMR confirmed the chemical structure of polymer. We demonstrate thermal stability of polymer which has hydrogen bonding by DSC, and explore the homogeneous phase. This binary blend system is able to form a miscible phase and supramolecular network structures due to the strong complementary multiple hydrogen bonding interactions between the A and T units. We also observe the ordered morphology of polymer through transmission electron microscopy(TEM). Finally, we investigated by UV-Vis spectroscopy and fluorescence spectroscopy (PL) which the effects of hydrogen bonding on the properties of materials.
