摘要：
Eight monoporphyrinate lanthanide complexes of the general formula [Ln(Por)(H2O)(3)]Cl (Ln = Yb3+ and Er3+, Por = tetraphenyl-porphyrin dianion (TPP2-)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. (C) 2003 Elsevier B.V. All rights reserved.
