Abstract :
Tris(bis(perfluorooctanoyl)methanato)neodymium(III), Nd(POM-D)3, was successfully synthesized to induced efficient emission in DMSO-d6. While the emission quantum yield of the tris(hexafluoroacetylacetonato)neodymium(III), Nd(HFA-D)3, system decreased as the concentration increased, the Nd(POM-D)3 system gave almost constant quantum yield (3.2%) in DMSO-d6 ranging in concentration from 0.01 to 0.07 M. The enhanced and characteristic emission of the Nd(POM-D)3 system suggests that dipole-dipole energy transfer via cross-relaxation through collisions between Nd3+ complex molecules should be suppressed in the fluid system by use of the bulky diketonato complex of Nd3+.
