| 摘 要： | A novel method for the preparation of chromogenic calixarenes with azo groups was reported.p-Substituted(-NO2,-CH3,-Cl)amilines were diazotized with isoamyl nitrite in EtONa/EtOH under refluxing condition.Fifteen mono-,bis-,tris-and tetrakis(p-substituted phenyl)azo calix4]arenes (including proximal and distal isomers) were obtainged respectively by diazo-coupling in different molar ratio to calix4]arenes(1) under pH=7.5-9.0 in non-aqueous solution at 0-5℃.^1H NMR and ^13C NMR spectra of (p-substtituted phenyl)azo calix4]-arenes indicated that they existed in cone conformation in solution.

| Abstract: | A novel method for the preparation of chromogenic calixarenes with azo groups was reported. p‐Substituted (‐ NO2, ‐ CH3, ‐ Cl) anilines were diazotized with isoamyl nitrite in EtONa/EtOH under refluxing condition. Fifteen mono‐, bis‐, tris‐ and tetrakis(p‐substituted phenyl)azo calix4]arenes (including proximal and distal isomers) were obtained respectively by diazo‐coupling in different molar ratio to calix4]arenes (1) under pH = 7.5–9.0 in non‐aqueous solution at 0‐5 °C. 1H NMR anduC NMR spectra of (α‐substituted phenyl)azo calix4]‐arenes Indicated that they existed in cone conformation in solution. |
