A functionalized monomer based on 3,4-propylenedioxythiophene, namely ProDOT-OH, was synthesized easily in a single step from commercially available starting materials and was successfully polymerized electrochemically resulting in the formation of an electroactive conjugated film on the working electrode. The presence of the free hydroxyl group makes ProDOT-OH as the material of choice due to ease of derivatization. This has been shown successfully for pre-polymerization functionalization wherein various derivatives were synthesized starting from ProDOT-OH. All the monomers were characterized by 1H, 13C NMR, GC-MS and elemental analysis. The polymers were characterized by cyclic voltammetry, spectroelectrochemistry and in situ conductance measurements.
一种基于3,4-亚丙基二氧噻吩的功能化单体,即ProDOT-OH,很容易从市售的起始原料通过一步合成制得,并成功地通过电化学聚合,在工作电极上形成了电活性的共轭薄膜。自由的羟基官能团使得ProDOT-OH易于衍生化,成为首选材料。这已经在预聚合功能化方面得到了成功应用,从ProDOT-OH出发合成了各种衍生物。所有单体均通过1H、13C核磁共振、气相色谱-质谱和元素分析进行了表征。聚合物则通过循环伏安法、光谱电化学和原位电导率测量进行了表征。
