Abstract

We have synthesized a porphyrin oscillator (1) composed of cerium(IV) bis(porphyrinate) bearing four peripheral zinc(II) porphyrinates. The rotational oscillation frequency of the porphyrin was evaluated in solution with and without the presence of diamine guest 2 by variable temperature NMR spectroscopy. The results established that the rotational frequency can be controlled by added guest utilizing positive homotropic allosterism.
