A series of novel redox-active triphenylamine-based materials, 4,4′-bis(4,4′-dimethoxydiphenylaminyl)-4′′-methoxytriphenylamine (BDATPA) and four related derivatives, including tris(4-methoxyphenyl)amine (TPA), N,N,N′,N′-tetrakis(4-methoxyphenyl)-1,4-phenylenediamine (TPPA), N,N,N′,N′-tetrakis(4-methoxyphenyl)-1,1′-biphenyl-4,4′-diamine (TPB) and tris(4-(4,4′-dimethoxyphenylaminyl)phenyl)amine (TPAPA)
一系列新型的具有氧化还原活性的三苯胺基材料,即4,4'-双(4,4'-二甲氧基二苯胺基)-4''-甲氧基三苯胺(BDATPA)和四个相关的衍生物,包括三(4-甲氧基苯基)胺(TPA)),N,N,N ',N'-四(4-甲氧基苯基)-1,4-苯二胺(TPPA),N,N,N ',N'-四(4-甲氧基苯基)-1,1'-联苯-4,4'-二胺(TPB)和三(4-(4,4'-二甲氧基苯基氨基基)苯基)胺(TPAPA),很容易制备,并研究了它们的电化学,光致发光(PL)和电致变色(EC)行为。有趣的是,只有TPB在溶液和固态中均显示出高PL强度,而其他TPB在溶液中均显示出低得多的PL强度。所有这些电活性材料均通过循环伏安扫描显示出优异的电化学可逆性,并在相关的氧化态下发生了多种颜色变化。此外,还采用了紫外可见光谱和光谱电化学测量来评估和计算摩尔消光系数,以利于这些材料成为调色板。
