Polyazulene (PAz) and polyazulene/graphene oxide composite (PAz/GO) films were electrochemically deposited from a choline based ionic liquid (IL), and characterized with attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) using Kretschmann geometry, and UV–Vis spectroscopy during electropolymerization and electrochemical oxidation. The use of different ILs has been shown to affect the morphology and long term cycling stability of PAz while fabricating composites is known to sometimes dramatically affect the electronic properties of PAz. The aim of this work was to study how the use of a viscous IL and, furthermore, incorporating GO affected the structural, electronic and optical properties of PAz. Overall, the vibrational behavior of the composite was very similar to PAz. During positive doping, the doping-induced infrared active vibrations (IRAV) of the composite were found at higher wavenumbers indicating shorter conjugation of PAz in the composite. Comparison to previous works and to PAz electropolymerized from conventional organic electrolyte solution revealed that polymerization in the viscous IL leads to electroactive and stable PAz with shorter effective conjugation length. The correlation between IRAV bands of doped PAz and Raman bands of neutral materials are also discussed within the framework of effective conjugation coordinate model (ECC).

从基于胆碱的离子液体（IL）电化学沉积聚氮丙稀（PAz）和聚氮丙稀/氧化石墨复合材料（PAz / GO）薄膜，并利用克雷奇曼几何形状和紫外线通过衰减全反射傅立叶变换红外光谱（ATR-FTIR）进行表征–电聚合和电化学氧化过程中的可见光谱。已显示使用不同的IL会影响PAz的形态和长期循环稳定性，而已知制造复合材料有时会极大地影响PAz的电子性能。这项工作的目的是研究粘性IL的使用以及GO的掺入如何影响PAz的结构，电子和光学性质。总体而言，复合材料的振动行为与PAz非常相似。在正掺杂期间，在较高的波数下发现了复合物的掺杂诱导的红外主动振动（IRAV），表明复合物中PAz的共轭时间较短。与以前的工作以及从常规有机电解质溶液中电聚合得到的PAz的比较表明，粘性IL中的聚合可产生电活性稳定的PAz，且其有效共轭长度较短。在有效共轭坐标模型（ECC）的框架内，还讨论了掺杂PAz的IRAV能带和中性材料的拉曼能带之间的相关性。与以前的工作以及从常规有机电解质溶液中电聚合得到的PAz的比较表明，粘性IL中的聚合可产生电活性稳定的PAz，且其有效共轭长度较短。在有效共轭坐标模型（ECC）的框架内，还讨论了掺杂PAz的IRAV能带和中性材料的拉曼能带之间的相关性。与以前的工作以及从常规有机电解质溶液中电聚合得到的PAz的比较表明，粘性IL中的聚合可产生电活性稳定的PAz，且其有效共轭长度较短。在有效共轭坐标模型（ECC）的框架内，还讨论了掺杂PAz的IRAV能带和中性材料的拉曼能带之间的相关性。
