制备了四种低聚三芳胺化合物（二胺1a、三胺1b、四胺1和五胺1d），并通过1H NMR、质谱和元素分析对其进行了表征。循环伏安法、方波伏安法、紫外-可见-近红外光谱电化学以及密度泛函理论的综合结果表明，化合物1a-1d分别表现出2至5步的氧化过程，对于相对较长的五胺，ΔE1/2和Kc值仍然显着，尽管它们都随着三苯胺单元的增加而降低。这四种化合物都表现出令人着迷的氧化还原调谐多重近红外吸收特性，并且每种化合物都可以同步实现完全可逆的多色电致变色。相关的单阳离子[1a]+–[1d]+可归类为适度耦合的Robin–Day II类混合价系统，该系统可通过至少两个相邻胺单元上的自旋离域来稳定。
Four oligomeric triarylamine compounds (diamine1a, triamine1b, tetramine1cand pentamine1d) were prepared and characterized by1H NMR, mass spectrometry and elemental analysis. The combined results of cyclic voltammetry, square-wave voltammetry and UV–vis–NIR spectroelectrochemistry, as well as density functional theory, reveal that compounds1a–1ddisplay two to five steps of oxidation processes, respectively, and the ΔE1/2andKcvalues were still remarkable for the relatively long pentamine, though they all decreased with an increase of the triphenylamine unit. These four compounds all exhibit fascinating redox-tuned multiple NIR absorption characteristics, and a completely reversible multicolor electrochromism for each of them could be synchronously realized. The associated mono-cationic [1a]+–[1d]+could be classified as moderately-coupled Robin–Day class II mixed-valence systems, which could be stabilized by spin delocalization over at least two adjacent amine units.
