产品说明 一般描述 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。 应用 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。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)
