The present invention relates to new calix arene compounds of formula (I). It also relates to their process of preparation. The present invention also relates to complexes between a compound of formula (I) and an element chosen among a metal, an actinide, a radioelement, a cationic guest or an anionic guest. The present invention also relates to a pharmaceutical composition comprising a compound of formula (I) in association with a pharmaceutically acceptable carrier. The present invention also relates to a process of preparation of water-soluble compounds, comprising a reaction of nitration or sulfonation or nitration, particularly of compounds of formula (I), and also to the compounds such as obtained.
calix[6]arene capped with a TAC unit is presented. The novel C3v-symmetrical calix[6](aza)cryptand displayed an exceptionally high affinity for small ammoniums. NMR and X-ray diffraction analyses demonstrated the formation of endo-complexes. These complexes are stabilized thanks to (i) hydrogen bonding to both the aza cap and one phenolic unit of the calixarene and to (ii) cationic and CH−π interactions
