Polyazomethines containing silane and phosphazene groups were synthesized via elimination reactions of dihydroxy compounds containing imine bonding with phosphazane and silane dichloride. The structures of monomers and polymers containing phosphazane and silane groups were supported by H-NMR, C-NMR, FT-IR and UV-Vis techniques. Electrochemical properties of the prepared Schiff bases and polymers were given by cyclic voltammetric (CV) analysis. Thermal properties of synthesized monomers and polymers were determined by TG-DTA and TG-DTA, DMA and DSC techniques, respectively. Molecular mass distributions of polymers are determined with gel permeation chromatography (GPC) measurement. Morphologic images of polymers containing heteroatom (silane/phosphazene) and azomethine linkage in the main chain were investigated by SEM techniques. The electrochemical band gap values of SB-1, SB-2, P-1, P-2 and P-3 compounds were found as 3.09, 3.30, 2.63, 3.07 and 3.04 eV, respectively.
通过含亚胺键的二羟基化合物与磷氮烷和二氯硅烷的消除反应合成了含硅烷和磷氮烯基团的聚甲亚胺。含磷氮烷和硅烷基团的单体和聚合物的结构通过(H-NMR)、(C-NMR)、傅里叶变换红外光谱（FT-IR）和紫外可见光谱（UV-Vis）技术得到证实。通过循环伏安法（CV）分析给出了所制备席夫碱和聚合物的电化学性质。分别通过热重-差示热分析（TG-DTA）、动态热机械分析（DMA）和差示扫描量热法（DSC）技术测定了合成单体和聚合物的热性质。用凝胶渗透色谱（GPC）测量法测定了聚合物的分子量分布。通过扫描电子显微镜（SEM）技术研究了主链中含杂原子（硅烷/磷氮烯）和甲亚胺键的聚合物的形态图像。发现化合物SB-1、SB-2、P-1、P-2和P-3的电化学带隙值分别为3.09、3.30、2.63、3.07和3.04电子伏特。
