Novel mono- and intermolecularly substituted, cyclized, and disazo dyes have been synthesized by the reaction of 4′-dimethylamino-2,3,4,5,6-pentafluoroazobenzene and perfluoroazobenzene with bifunctional heteroatom nucleophiles, such as 1,2-benzenedithiol, 2-aminobenzenethiol, 2-aminophenol, 1,2-ethanedithiol, ethylenediamine, and 2-aminoethanol. The kinds of bifunctional nucleophiles and the reaction
通过 4'-二甲氨基-2,3,4,5,6-五氟偶氮苯和全氟偶氮苯与双功能杂原子亲核试剂(如 1,2-苯二硫醇、 2-氨基苯硫醇、2-氨基苯酚、1,2-乙二硫醇、乙二胺和2-氨基乙醇。双功能亲核试剂的种类和反应条件极大地影响了产物的分布。这些染料的吸收最大值和摩尔吸收系数分别在 323-485 nm 和 15000-60000 dm mol-1 cm-1 范围内观察到。
