The functionalisation of two neighboring β-pyrrolic positions of a porphyrin by a fused N-heterocyclic carbene ligand, the subsequent metallation of this external coordination site by palladium(II) and the structural characterisation of the resulting compounds are presented.
positions and their two new non-sandwich-type ytterbium(III)-porphyrin coordination compounds have been synthesized. New porphyrin compounds and the two coordination compounds were characterized by Nuclear Magnetic Resonance, High Resolution Mass Spectrum, Ultraviolet and visible, and fluorescence in the visible and Near Infrared (NIR) regions. The two Yb(III) complexes afforded the photoluminescence quantum
