Abstract

Eight monoporphyrinate lanthanide complexes of the general formula [Ln(Por)(H₂O)₃]Cl (Ln=Yb³⁺ and Er³⁺, Por=tetraphenylporphyrin dianion (TPP^2-) and its para-substituted derivatives) were prepared and characterized by elemental analyses, MS, IR and UV-Vis spectra. Photoluminescence studies showed that porphyrinate dianion absorbed the visible light, transferred the energy to lanthanide ions and enabled the later emitting in the near-infrared region. The effects of substituent and solvent on the photoluminescence efficiency were also discussed.
