摘要: | 本计画之主要目的系设计及合成數系列5-7 熔合杂环之共轭高分子,并应用于有 机薄膜电晶体。第一年将设计三种以咔唑为核心之5-7 熔合杂环单体;第二年将设计 并合成三种以苯并双噻吩与葱为核心之5-7 熔合杂环单体;第三年将设计并合成一种 以双并噻吩为核心之6 熔合杂环单体。这些单体之有机锡衍生物将分别与噻吩、双噻 吩及双并噻吩之溴化物,利用Stille 偶合聚合反应,总共合成出十五种共轭高分子,所 合成之高分子将应用于有机薄膜电晶体之制备上。 所制备之 5-7 熔合杂环单体,将利用蒸镀方法制备有机薄膜电晶体,本研究将探 讨热蒸镀速率、基材温度、基材表面处理剂及回火温度对于薄膜特性之关系,所合成 之十五种共轭高分子将以旋转涂布法制备成有机薄膜电晶体,本研究将探讨旋转涂布 速率、回火温度及表面处理剂与薄膜品质及形态学之关系,最后将量测所制备有机薄 膜电晶体之载子迁移率、驱动电压及开关比。 This proposal is aimed to design and synthesize several series of conjugated polymers based on 5-7 fused heterocyclic rings. The synthesized polymers are used for the application in organic thin film transistor. In the first year, three kinds of 5-7 fused ring moieties (i.e. CzDTB, CzDTP and CzDTSi) based on a carbazole unit are synthesized. In the second year, three kinds of 5-7 fused ring moieties (i.e. BDTDT, aADT and BDTDCPT) based on benzodithiophene and anthracene unit are synthesized. In the third year, a hexacyclic fused ring moiety (TTDCPT) based on thienothiophene unit is prepared. Their organo-tin derivatives of the synthesized 5-7 fused ring moieties are polymerized with dibromo-derivatives of thiophene, bithiophene and thienothiophene through Stille coupling to yield 15 kinds of conjugated polymers. We fabricate the OTFT devices based on the 5-7 fused ring monomers by a thermal evaporation method. Films deposited on octadecyltrichlorosilane (OTS) – treated SiO2 substrates under properly adjusted substrate temperature, thermal evaporation rate, and annealing temperature, achieve a good film quality. The synthesized polymers are used to fabricate OTFT devices through a spin coating process. The film quality and morphology are controlled by spin coating rate, thermal annealing temperature and surface modification agents. The OTFT characteristics including mobility, turn-on voltage and Ion / Ioff ration are evaluated. |
