Synthesis, structure and luminescent properties of a new praseodymium() complex with β-diketone
2003
A new tetrakis praseodymium(tu) complex Pr(TFNB)(3)Phen has been synthesized, in which TFNB is 4,4,4-trifluoro-1-(2-naphthyl)-1,3-butanedione and Phen is 1,10-phenanthroline. Its crystal structure and luminescent spectra were successfully determined and investigated. The typical antenna effect existing in the luminescence of Pr(TFNB)(3)Phen was revealed by the study of the UV-Vis absorption spectra of ligands and the excitation spectrum of Pr(TFNB)(3)Phen.
