Abstract A fluorinated diamine, 1,3-bis(4-amino-2-trifluoromethylphenoxy)benzene (mBATB), was synthesized through nucleophilic substitution reaction of Resorcinol and 2-chloro-5-nitrobenzotrifluoride by catalytic reduction with H 2 gas and Pd/C. The synthesis and properties of a series of soluble fluorinated aromatic polyimides derived from mBATB and various dianhydrides via thermal and chemical imidization were described. Substituents of trifluoromethyl groups on the aromatic rings of metalinked ether aromatic diamine conferred enhanced solubility and transparency to the polyimide. The polyimides with various dianhydrides: 4,4′-benzophenonetetracarboxylic dianhydride (BTDA), 4,4′-oxydiphthalic anhydride (ODPA) and 4,4′-(hexafluoroisopropylidene) diphthalic anhydride (6FDA) also exhibited exceptional thermal stability, comparatively low dielectric constants, and excellent optical properties. The outstanding features of the synthesized transparent polyimides are desirable candidate materials for advanced optoelectronics applications.

基于 1,3-双(4-氨基-2-三氟甲基苯氧基)苯的浅色氟化聚酰亚胺的光学和介电特性

摘要 以间苯二酚和2-氯-5-硝基三氟苯经H 2 气体和Pd/催化还原的亲核取代反应合成了一种氟化二胺1,3-双(4-氨基-2-三氟甲基苯氧基)苯(mBATB)。 C。描述了通过热和化学酰亚胺化从 mBATB 和各种二酐衍生的一系列可溶性氟化芳族聚酰亚胺的合成和性能。金属联醚芳族二胺的芳环上的三氟甲基取代基赋予聚酰亚胺增强的溶解性和透明度。具有各种二酐的聚酰亚胺：4,4'-二苯甲酮四羧酸二酐（BTDA）、4,4'-氧二邻苯二甲酸酐（ODPA）和 4,4'-（六氟异亚丙基）二邻苯二甲酸酐（6FDA）也表现出优异的热稳定性，相对较低的介电常数和优异的光学性能。合成的透明聚酰亚胺的突出特点是先进光电子应用的理想候选材料。
