meso-Trifluoromethyl-substituted subporphyrin was obtained through an extrusion reaction from meso-trifluoromethyl-substituted heptaphyrin(1.1.1.1.1.1.1) upon combined metallation of Cu(II) and B(III) ions. The subporphyrin exhibited the most blue-shifted Soret-like absorption band among those ever prepared.
