在三氟化硼乙醚及其混合电解质中,吲哚及其衍生物阳极氧化可以获得高质量的聚吲哚及其衍生物膜:聚吲哚、聚(5-甲基吲哚)、聚(5-硝基吲哚)、聚(5-氰基吲哚)、聚(5-溴吲哚)。它们可溶于DMSO和THF中。聚吲哚及其衍生物具有良好的荧光性质;单体的发射光谱与取代基有关,而聚合物的发射光谱几乎不受取代基的影响。电子离域程度增大,使得聚合物的激发和发射光谱红移,宽的分子量分布则会使聚合物的激发和发射光谱变宽。
Anodization of indole and its derivatives in high purity polybenzazole and its derivative films can be obtained in boron trifluoride etherate and its mixed electrolyte: polyindole, poly (5-methylindole), poly Nitroindole), poly (5-cyanoindole), poly (5-bromoindole). They are soluble in DMSO and THF. Polybenzotriazole and its derivatives have good fluorescence properties; the emission spectra of the monomers are related to the substituents, while the emission spectra of the polymers are almost unaffected by the substituents. The degree of electron delocalization increases, which causes red shift of the excitation and emission spectra of the polymer. The wide molecular weight distribution broadens the excitation and emission spectra of the polymer.
