dc.description.abstract本論文合成了含有fluorene和phenylenevinylene的衍生物之共聚合體,我們使用的方法為 Wittig-Horner Reaction,合成出P(FV-PV) 和P(FV-PV-triptycene)。P(FV-PV)和P(FV-PV-triptycene)具有相同主鏈結構,但P(FV-PV-triptycene)比P(FV-PV)多了triptycene的巨大側鏈基團,可研究含有triptycene側鏈基對高分子性質的影響。 由P(FV-PV)薄膜的吸收光譜可看出,在基態分子間就有嚴重的堆疊,且放光波長比P(FV-PV-triptycene)紅位移。在溶解度方面,P(FV-PV-triptycene)因巨大側基所造成的立體阻礙使分子鏈堆疊較不緊密,致使溶解度更優於P(FV-PV)。在熱性質方面,triptycene 的側鏈基加強分子鏈的剛硬度,進而提高高分子的熱穩定性,經由薄膜熱處理,P(FV-PV-triptycene)仍舊維持其光色穩定性,而P(FV-PV)薄膜加熱處理後,高分子鏈產生了運動,因而增加分子堆疊的可能性,使得激發複合體形成。zh_TW
dc.description.abstractIn this thesis we report the synthesis and characterization of two poly(fluorenevinylene-co-phenylenevinylene) copolymers, P(FV-PV) and P(FV-PV-triptycene). We have also studied comparatively their solubility, optical properties, and thermal properties. The two polymers, which contain alternating fluorenevinylene and phenylenevinylene units in the main chain, are synthesized via Wittig-Horner Reaction. In the case of P(FV-PV-triptycene), the bulky tryptycene groups are introduced as side chains to the polymer backbone. Attributed to the presence of the rigid bulky triptycene pendants, P(FV-PV-triptycene) exhibits a improved solubility and thermal properties, and the degree of aggregation in solid state is significantly reduced. The results from the photoluminescence measurements of the isothermally heated two copolymers thin films (100 oC for 10h) show that P(FV-PV-triptycene) still performs the same color emission without aggregates or excimers formation.en_US
