In the case of the unsaturated alcohols , such as hydroxyethyl acrylate ( hea ) , the paes showed the photo - alignment property to the nematic liquid crystals with the pretilt angle of 0 . 60 ? secondly , three kinds of fluoro - containing diamine monomers were prepared via the reduction reactions of the corresponding dinitro compounds , which were synthesized via the nitro nucleophilic displacement reactions of 3 , 5 - dinitro - 5 - trifluoromethyl benzene with diphenol compounds 此外，本论文还设计并通过3 ， 5 -二硝基三氟甲苯与二酚化合物的硝基亲核取代反应制备了二硝基化合物，将其还原最终合成了三种间位取代的含氟二胺单体tfpda 、 tfbpda与tfmda ，并对其聚合行为进行了研究。
