【摘要】 研究了碱式聚苯胺的共振、预共振和正常拉曼光谱及其电化学反掺杂的现场拉曼光谱,对比相应模型化合物的光谱,对其谱带作了归属。光谱特性表明聚苯胺链结构是由苯二胺和醌二亚胺单元组成的。其摩尔比约1:1,因电荷在链上的离域,二者发生了轻微变异。更多还原

【Abstract】 Normal, resonant and pre-resonant Raman spectra of polyaniline (PAn) in base form, in situ Raman spectra of electrochemically-dedoped PAn were observed. The assignments of the spectra of PAn in base form were made, comparing with that of related model compounds. The spectral features suggest that the chain of PAn consists of benzene diamine and quinone diimine, whose molar ratio is abuot 1∶1 and which are slightly modified due to charge delocalization along the chain.更多还原
