用3,3’,4,4’-联苯四甲酸二酐(BPDA)和5,5’-(六氟异丙基)-二-(2-氨基苯酚)(6FHP)合成了含氟聚酰亚胺有机聚合物。首先是合成了经酰胺化的主链上带有活性羟基的含氟聚酰亚胺,再通过Mitsunobu反应将活性生色分子分散红19(DR19)共价链接到聚酰亚胺的侧链骨架上而得。采用衰减全反射测定了聚合物的折射率和热光系数,该聚酰亚胺具有较大的热光系数,在650nm处其值为-2.72147×10-4℃-1,这为研制具有低驱动功率的新型数字热光开关具有一定意义。
Fluoropolyethers were synthesized using 3,3 ’, 4,4’-biphenyltetracarboxylic dianhydride (BPDA) and 5,5’ - (hexafluoroisopropyl) -bis- (2- aminophenol) (6FHP) Imide organic polymer. Firstly, a fluorinated polyimide with active hydroxyl groups on the amidated main chain was synthesized, and then the active chromogenic molecule dispersion red 19 (DR19) was covalently linked to the side chain skeleton of the polyimide through the Mitsunobu reaction Come on. The refractive index and the thermo-optic coefficient of the polymer were measured by attenuated total reflection. The polyimide has a large thermal coefficient of -2.72147 × 10 -4 ° C. -1 at 650 nm, The new digital thermo-optic switch that drives power has some significance.
