Abstract

The solubility enhancement effect of N-substitution and increasing size of the N-substituent in octaethyl- and tetraphenylporphyrins is strongly dependent of the electronic nature of the β- and meso-sub- stituents. It is suggested that N-alkyl(aryl) substitution exerts primarily distorting rather than polarizing effect on the porphyrin macroring.
