2，5-噻吩二甲酸 (2，5-TDCA，H 2 TDC) 是制备荧光增白剂、杀菌剂和抗癌药物的重要原料。己二酸用氯化亚砜氯化生成。由于其配位方式的多样性，它作为芳香连接物是生成配位网络的极佳选择。用旋转弹燃烧量热法计算了 2，5-噻吩二甲酸的燃烧焓和升华焓。2，5-噻吩二甲酸可作为噻吩基连接基团用于镁配位网络的制备。[6]也可作为合成 2，5-二苯并恶唑噻吩 (EBF) 的前体。 可用于以下合成： · 新型噻吩二甲酸钴配位聚合物 · 新型介晶噻吩类超分子液晶 · 两种新型配位聚合物，分子式为 {[Ln2(2,5-tdc)3(dmso)2]H2O}n (Ln = Tb(III) and Dy(III)), (2,5-tdc2 = 2,5-噻吩二甲酸酯和 dmso = 二甲亚砜） 2,5-Thiophenedicarboxylic acid (2,5-TDCA, H2TDC) is an important building block in the preparation of fluorescent brightening agent, fungicides and anti-cancer drug. It has been generated by chlorination of adipic acid using thionyl chloride.Due to its diverse coordination modes, it is an excellent choice as an aromatic linker to generate coordination networks. The enthalpies of combustion and sublimation of 2,5-thiophenedicarboxylic acid have been evaluated by rotary-bomb combustion calorimetry.
