Covalent fixation of the cyclic tetramer of a metallo-porphyrin based on self-complementary quadruple hydrogen bonding
The stability of quadruple hydrogen bonding in the cyclic tetramer of a metallo-porphyrin before and after a covalent fixation was investigated. According to competition and energy-transfer experiments, the exchange reaction between the cyclic tetramers of the metallo-porphyrin was fully suppressed by the covalent fixation. This spontaneous cyclization-covalent fixation strategy based on olefin metathesis can open the way to the use of cyclic assemblies in a solid phase.
