Abstract Tailoring of conjugated monomers via copolymerization is a facile method to obtain tunable spectral, morphological and optical properties. To investigate the effect of copolymerization of pyrrole with o-phenylenediamine on the optoelectronic properties of the synthesized copolymers, the present work reports the synthesis of copolymers of o-phenylenediamine with pyrrole with varying mol ratios via chemical polymerization in methylene blue (MB) medium. Copolymerization was confirmed by Fourier transform infrared spectroscopy and ultraviolet-visible studies. Ultraviolet-visible spectroscopy revealed variation in the optical properties with the change in the monomer ratio. Fluorescence studies showed that the copolymer containing 80% poly(o-phenylenediamine) revealed highest quantum yield among all the copolymers. The emission color could therefore be tuned by careful selection of narrow band co-monomers, which could help in designing tunable fluorescence emitting materials for potential application in OLED devices.

通过模板介导的共聚调节聚（邻苯二胺-共-吡咯）的光学性质

摘要 共轭单体共聚是一种获得可调光谱、形态和光学性质的简便方法。为了研究吡咯与邻苯二胺共聚对合成共聚物光电性能的影响，本工作报告了在亚甲蓝 (MB) 介质中通过化学聚合合成不同摩尔比的邻苯二胺与吡咯共聚物。通过傅里叶变换红外光谱和紫外-可见研究证实了共聚。紫外-可见光谱揭示了光学性质随单体比例的变化而变化。荧光研究表明，含有 80% 聚（邻苯二胺）的共聚物在所有共聚物中显示出最高的量子产率。
