摘要：

This article describes the synthesis, structure end UV properties of azocalixcrowns in which the photoresponsive trans-cis azo benzene unit has been introduced in the glycolic chains of the calix[4]crowns. The synthesis proceeded via the selective- 1,3 O-dialkylation of calix[4] arene with glycolic chains terminated by nitrophenyl residues. After reduction of the nitro groups into amino functions, intramolecular oxidative coupling produced the capping of the calixarene. The synthetic approaches and the cis-trans structure of these new ligands are discussed and full details on syntheses and structural data are given. A preliminary example of cesium complexation by one of the ligands is proposed.
