Abstract

A series of gadolinium(III) porphyrinate complexes was synthesized in moderate yield from the interaction of meso-substituted porphyrin free bases with Ln[N(SiMe3)2]3·x[LiCl(THF)3], followed by the addition of a tripodal anion LOMe-- 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.
