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.

carboxylic acid), situated in the gamma or epsilon position of the phenoxy moieties, deactivates the corresponding aromatic ring by removing electron density through intramolecular hydrogen bonding. The high control operated by the O-substituents at the small rim even allowed the selective ipso-nitration of partially detertiobutylated calixarene 1(H3). Hence, these findings open new routes to a wide range of
