Аннотация:A series of mixed porphyrins with different numbers of metallocenyl (ferrocenyl and cymantrenyl) and aryl (Ph and C6F5) groups at the meso-positions was obtained and characterized by 1H NMR, electronic absorption, and mass spectra. The downfield shift of NH signals as well as the bathochromic shift of Q-bands can be attributed to a distortion of the porphyrin macrocycle upon the introduction of bulky meso-substituents.
