Popis: The p-arylazo-substituted calix[4]arenes were synthesized by a diazo- coupling reaction between calix[4]arene and the diazonium salt of 6-amino-1,3-benzodioxin. The monoarylazo-, 1,2-diarylazo-, 1,3-diaryl- azo- , triarylazo-, and tetraarylazo-para-substituted calix[4]arenes were isolated and characterized by spectral methods. 6-Amino-1,3-benzo- dioxin was prepared by palladium metal reduction of 6-nitro-1,3-benzo- dioxin
