A series of gadolinium(III) porphyrinate complexes was synthesized in moderate yield from the interaction of meso ‐substituted porphyrin free bases with Ln[N(SiMe 3 ) 2 ] 3 · x [LiCl(THF) 3 ], followed by the addition of a tripodal anion L OMe – – an effective encapsulating agent for lanthanide ions. These new complexes were fully characterized by X‐ray crystallography, elemental analysis, mass spectrometry, and infrared spectroscopy. The electronic spectra show a near‐infrared phosphorescence from the triplet state of the porphyrin rings and exhibit a very characteristic vibronic‐structured emission.
