“…Meanwhile, the use of TMSBr for hydrolysis of In-1b led to the complete removal of metal atoms from the porphyrin macrocycle, as was observed previously for tetraazaporphyrins, , and the partial hydrolysis of one ethyl group to give the free monoester of the meso -porphyrinylphosphonic acid 2H-2b . Nevertheless, the addition of triethylamine to the reaction mixture prevents C–P bond cleavage, and the formation of triethylammonium salts of Ga-4a – Ga-4c and In-4a – In-4c after the addition of MeOH occurs in quantitative yields.…”

The synthesis and structural characterization, both in solution by means of H andP NMR and UV-vis spectroscopies and in the solid state by X-ray diffraction on single crystal, of a series of gallium(III) and indium(III) meso-mono(diethoxyphosphoryl)porphyrins bearing different peripheral substituents as well as the corresponding monoesters and phosphonic acids are reported. This work describes the first example of the X-ray structure of a self-assembled dimer formed via strong binding between the oxygen atom of the phosphonate substituent and the gallium(III) cations of adjacent porphyrin molecules [Ga-O = 1.9708(13) Å].
