通过三步法合成了一系列由1,4-亚苯基间隔基与1-丁基吡啶鎓受体环共轭的N,N-二甲基氨基苯基供体基团组成的溶剂化染料。该程序涉及4-溴苯基吡啶鎓盐的合成,它们向N-丁基吡啶鎓衍生物的转化以及钯催化的Suzuki-Miyaura偶联反应。他们的紫外线-可见光谱行为,在13种溶剂中进行了研究,并与Reichardt's E T(30)甜菜碱的氨基类似物的溶剂溶变色进行了比较。所有合成的染料均显示出反相溶剂变色现象,这通过理论计算是合理的。

1-butylpyridinium acceptor ring through a 1,4-phenylene spacer were synthesized by a three-step procedure. The procedure involved the synthesis of 4-bromophenylpyrylium salts, their conversion to N-butylpyridinium derivatives, and palladium-catalysedSuzuki–Miyaura coupling reactions. Their UV-vis spectroscopic behaviours, which were investigated in 13 solvents, were compared with the solvatochromism of an
