摘　　要：通过酰化反应和偶联反应合成了小分子单体1,3-双[3,5-二戊氧基苯甲酰(3-氨丙基)]-1,1,3,3-四乙氧基二硅氧烷(M),并采用红外光谱(FTIR)、核磁共振谱(1H_NMR)及X-射线衍射(XRD)对其进行了表征.在酸性条件下,通过固相反应成功地由M制备了一种高分子杂化材料,并利用29Si_NMR,XRD,FTIR和差热分析(DSC)对这种材料进行了表征,其结果表明这种杂化材料的大分子主链上明显具有规整且长程有序的梯形结构.不同温度下的固相反应表明:由于小分子的扩散明显依赖于温度,因此温度对固相反应速率具有很大的影响.The monomer 1, 3-bis [3, 5-dipentoxybenzoyl （3-aminopropyl）]-1, 1, 3, 3-tetraethoxydisiloxane （M） has been synthesized via coupling reaction in this work. The solid state polycondensation was successfully employed to get a novel hybrid material with ladderlike structure at 60 ℃ . On base of FTIR, DSC, XRD and 29 Si-NMR measurements, it is found that a long-range ordered ladderlike structure exists on the macromolecular chain of the hybrid material. The comparative experiment under different temperature indicates that reaction temperature has considerable effect on the solid state polycondensation of monomer due to the diffusion mechanism.
