The poly(azomethine)s containing pyridine ring were synthesized in two stages and analyzed by electrochemical, optical and thermal analysis techniques. Pyridine with centric dialdehyde (DA-Py) and poly(azomethine-pyridine)s (PAZ-Py)s were synthesized by elimination and condensation reactions in organic solvent medium, respectively. The structures of the synthesized dialdehyde and poly(azomethine-pyridine)s were verified by nuclear magnetic resonance spectroscopy (NMR), Fourier-transform infrared spectroscopy (FT-IR) and ultraviolet–visible spectroscopy (UV–Vis) analysis was performed and they were also characterized with cyclic voltammetry (CV), photoluminescence (PL) analysis, thermal analysis (TG-DTA) and Differential Scanning Calorimetric (DSC) analysis. According to thermal analysis, the initial degradation temperature (T_on) and glass transition temperature (T_g) values of PAZ-Py-1, PAZ-Py-2 and PAZ-Py-3 were found to be 126, 185, 139 °C and 102, 153 and 125 °C, respectively. According to fluorescence analysis, PAZ-Py-1 emitted four different colors of blue, green, orange and red emissions when excited at different wavelengths such as 340, 360, 380, 400, 420, 440 nm; 460, 480 nm; 500 nm; and 580 nm, respectively, in dimethylformamide (DMF) solutions. Also, two different colors were observed when excited at different wavelengths (blue emissions at 280, 300, 320, 340, 360, 380, 400, and 440 nm and orange emissions at 460, 480, 500, 520, 540, and 560 nm) in ethanol (EtOH) solutions. In addition, fluorescence quantum yields of PAZ-Py were found to be 9.0% and 11.0%; and 9.0% and 9.5% when excited at 440 and 460 nm in EtOH solution and when excited at 380 and 400 nm in DMF solutions, respectively.

含吡啶环的聚（偶氮甲碱）分两个阶段合成，并通过电化学，光学和热分析技术进行分析。通过在有机溶剂介质中进行消除和缩合反应，分别合成了带有中心二醛的吡啶（DA-Py）和聚（偶氮甲碱-吡啶）（PAZ-Py）。核磁共振波谱（NMR），傅立叶变换红外光谱（FT-IR）和紫外可见光谱（UV-Vis）分析验证了合成的二醛和聚（甲亚胺吡啶）的结构，并进行了分析还通过循环伏安法（CV），光致发光（PL）分析，热分析（TG-DTA）和差示扫描量热法（DSC）分析对其进行了表征。根据热分析，初始降解温度（T_on）和玻璃化转变温度（T _g）PAZ-Py-1，PAZ-Py-2和PAZ-Py-3的值分别为126、185、139°C和102、153和125°C。根据荧光分析，当在不同波长（例如340、360、380、400、420、440 nm）激发时，PAZ-Py-1发出四种不同颜色的蓝色，绿色，橙色和红色发光。460，480纳米; 500纳米; 在二甲基甲酰胺（DMF）溶液中分别为580 nm和580 nm。此外，当以不同的波长激发时，观察到两种不同的颜色（280、300、320、340、360、380、400和440 nm处的蓝色发射和460、480、500、520、540和560 nm处的橙色发射）溶于乙醇（EtOH）溶液中。另外，发现PAZ-Py的荧光量子产率为9.0％和11.0％。当在EtOH溶液中在440和460 nm处激发时以及在DMF溶液中在380和400 nm处激发时，分别为9.0％和9.5％。
