一种含芴或芴酮结构的具有高平面性二胺单体及其合成方法和应用
摘要：
本发明公开的是一种含芴或芴酮结构具有高平面性的二胺单体及其合成方法和应用。本发明利用二卤代芴或芴酮的卤原子与氨基反应形成仲胺；或利用二卤代芴或芴酮经氰化、水解、酰氯化反应得到酰氯，再利用酰氯与氨基形成酰胺键；或利用二硝基芴或芴酮得到氨基，再利用氨基与异氰酸酯形成脲键；或利用二卤代芴或芴酮经Suzuki、还原反应得到氨基，再利用氨基与卤原子形成仲胺；或利用二卤代芴或芴酮与羟基反应形成醚键。最后将含仲胺、酰胺键、脲键和醚键的二硝基还原成二胺。本发明的二胺单体的最低能态3D结构具有高平面性，以其为单体可制备分子链间相互作用力强、自由体积小的聚酰胺、聚酰亚胺、聚酰胺酰亚胺和聚脲酰亚胺等聚合物。
摘要（英）：

The invention discloses a high-planarity diamine monomer containing a fluorene or fluorenone structure and a synthesis method and application thereof.Halogen atoms of dihalogenation fluorene or fluorenone react with amidogen to form secondary amine; or dihalogenation fluorene or fluorenone is subjected to cyaniding, hydrolysis and chloroformylation reaction to obtain acyl chloride, and then an amido bond is formed by means of acyl chloride and amidogen; or binitro fluorene or fluorenone is used to obtain amidogen, and then a urea bond is formed by means of amidogen and isocyanate; or dihalogenation fluorene or fluorenone is subjected to Suzuki and reduction reaction to obtain amidogen, and secondary amine is formed by means of amidogen and halogen atoms; or dihalogenation fluorene or fluorenone reacts with hydroxyl to form an ether bond.Finally, binitro containing secondary amine, amido bond, urea bond and ether bond is reduced to be diamine.The lowest energy state 3D structure of the diamine monomer has high planarity, and by means of the diamine monomer, polymers such as polyamide, polyimide, polyamideimide and polyureas-imide with high inter-molecular-chain interaction force and small free volume can be prepared.
