Heck and Sonogashira cross-coupling reactions have been used for the functionalization of the upperrim of a tetraiodinated calix[4]arene. In this way, oligophenylenevinylene (OPV) and oligophenyleneethynylene (OPE) arrays have been constructed on the calix[4]arene core to produce covalent assemblies of four π-conjugated chromophores. Electrochemical properties have been investigated by cyclic voltammetry
