The porphyrin-stoppered rotaxane was prepared from dibenzo-24-crown-8 (DB24C8) and the secondary ammonium ion derivative end-capped by the axial coordination of rhodium(III) tetra- (3,5-di-tert-butylphenyl) porphyrin [TBPP Rh(III) Cl]. This rotaxane molecule was designed aiming at the immobilization on a substrate and the analysis of the physicochemical properties as a single molecule.
