4-[2-ferrocenylethenyl]phenyl group and with significant electronic absorption in the near infrared have been prepared via acidification of the tertiary carbinols obtained by reaction of 4-[FcCHCH]C6H4Li with diethyl isophthalate, diethyl terephthalate, diethyl phthalate or the triethyl ester of 1,3,5-benzene carboxylic acid. Even more stable dyes were prepared from two new triarylmethanol derivatives containing 2,
通过酸化4- [FcCHCH] C 6 H反应获得的叔甲醇,制备了一系列新的强烈着色的多电荷的含4- [2-二茂铁基乙烯基]苯基并且在近红外具有明显电子吸收的多甲基鎓化合物。与间苯二甲酸二乙酯,对苯二甲酸二乙酯,邻苯二甲酸二乙酯或1,3,5-苯甲酸三乙酯形成4 Li。用两种新的含2,6-二甲氧基-4- [2-(二茂铁基)乙烯基]苯基或2,6-二甲氧基-4- [2- [4-(二甲基氨基)苯基]乙烯基的三芳基甲醇衍生物制备了更稳定的染料。通过4- [FcCHCH] -2,6-MeO 2 C 6 H 2 Li或4- [4-Me 2 NC6 H 4 CHCH] -2,6-MeO 2 C 6 H 2 Li(Fc =二茂铁基)与碳酸二乙酯。这些甲醇在用酸处理时会沉积出暗紫色晶体,该晶体已被分离并通过光谱表征。它们在近红外线中吸收,而它们的溶液仅在几天后才开始脱色,但它们对固态的空气和湿气显示出长期稳定性。
