摘要
以碘代芳烃与芳基硼酸在钯催化下的Suzuki交叉偶合反应为关键步骤,采用收敛法成功合成了一系列结构不对称的含噁二唑π-共轭寡聚芳烃OX-Ph3An,OX-Ph3Np和OX-Ph3TPA,并对它们的结构、热学性质、光学性质和电化学性质进行了表征。结果表明:新合成的不对称含噁二唑π-共轭寡聚芳烃具有很高的热稳定性(Tdec=487-517℃)和较高的玻璃态转化温度(Tg=91-112℃)。
A series of unsymmetrically oxadiazole-based π-conjugated oligoarylenes,OX-Ph3An,OX-Ph3Np and OX-Ph3TPA had successfully been synthesized by a divergent approach using Pd-catalyzed Suzuki cross-coupling reaction of iodo-oligoarylene and arylboronic acid as a key step.Their optical,electro-chemical and thermal properties had also been characterized. These novel synthesized oxadiazole-based oligoarylenes showed highly glass transition temperatures( Tg= 91 - 112℃) and thermal stabilities( Tdec=487 - 517℃).
