| 摘 要： | 以含氟的二胺5，5’-（六氟异丙基）-二-（2-氨基苯酚）（6FHP）及二酐4，4’-（六氟异丙基）-苯二酸酐（6FDA）或均苯四甲酸酐（PMDA）为单体，以分散红1（DR1）为活性生色分子合成具有非线性光学特性的含氟聚酰亚胺，并采用溶胶-凝胶（Sol—Gel）法合成相应的聚酰亚胺／SiO2杂化材料。采用固态^29SiMASNMR谱研究了含氟聚酰亚胺／SiO2杂化材料的交联结构，结果表明杂化材料中是以T^3、Q^3、Q^4结构为主，说明在杂化材料中形成了交联网状结构．采用衰减全反射（ATR）测定了聚酰亚胺和杂化材料在832nm处的电光系数，其值分别为32、28、34和29pm／V，结果表明具有较高的电光系数。

| Abstract: | The fluorine-containing polyimides with nonlinear optical were synthesized using the monomers 2,2-bis(3-amino-4-hydroxy phenyl) hexafluoropropane (6FHP), 4,4'-(hexafluoroiso-propylidene) diphthalic anhydride (6FDA) or pyromellitic dianhydride (PMDA) and Dispered Red 1 (DR1) as an active chromophore. The hybrid materials were obtained with Sol-Gel technique. 29Si nuclear magnetic resonance spectroscopy were used to characterize the structure of the polyimide/ SiO2 hybrid. The results revealed that Q3, Q4 and T3 were the major microstructure forming a network structure. The electro-optic coefficients of nonlinear optical polymers and hybrids were measured by attenuated-total-reflection (ATR) technique. They were 32,28,34 and 29 pm/V, separately. Their results showed that they had high EO coefficients. |
