Meso-substituted liquid porphyrins.
Meso-substituted A(4)-porphyrins bearing 3,4,5-trialkoxyphenyl substituents are efficiently synthesized and characterized. Porphyrins bearing twelve C10 and C11 alkyl chains turned out to be liquid at room temperature. The remaining porphyrins, bearing C8, C9, C12, and C18 alkyl chains, have low melting points and high solubility in nonpolar solvents. Their differential scanning calorimetry distinctly shows, in most cases, only one phase transition.
