✦ Synopsis

Abstract

A soluble praseodymium complex was synthesized using a polymeric PUDS ligand. FTIR and Raman spectra suggest that the >NH lone pair in PUDS can interact with the Pr^3+^ centers. DSC results show that the coordination effect causes a significant increase of the phase transition temperature. The emission spectrum of Pr‐PUDS indicates an efficient energy transfer from the macromolecular ligand to the coordinated Pr^3+^ ion. The magnetic behavior as function of applied magnetic field or temperature (50–450 °C) and some unusual transitions in the M versus T plots are reported and discussed, which demonstrate that the magnetic properties of the Pr‐PUDS strongly depend on the phase transition.
