Self-organization of porphyrin units induced by magnetic field during sol–gel polymerization

Abstract

The use of a magnetic field as a controlling factor during the hydrolysis–polycondensation of porphyrin precursors substituted by Si(OR)₃ groups, induces a self-organization of porphyrin moieties due to the stacking of these units in the hybrid material and this study also confirms the effect of the magnetic field in the nano- and micrometric organization during the kinetically controlled polycondensation process.
