4.1 Synthesis of calix[4]tetra-anilines and grafting of the corresponding calix[4]arenes

Calix[4]tetra-aniline precursors are synthesized from the commercially available para-tert-butyl-calix[4]arene. Para-tert-butyl-calix[4]arenes are first functionalized on the small neck with alkyl, fluoroalkyl or carboxylic acid groups according to conventional procedures developed in the literature. An ipso-nitration reaction followed by a reduction step finally leads to the formation of calix[4]tetra-anilines.

In a first approach, several compounds are synthesized (figure 5 ):
