  Luminescence Properties and Quenching Mechanisms of Ln(Tf₂N)₃ Complexes in the Ionic Liquid bmpyr Tf₂N

  摘要：

  The emission properties, including luminescence lifetimes, of the lanthanide complexes Ln(Tf2N)(3) (Tf2N = bis-(trifluoromethanesulfonyl)amide); Ln(3+) = Eu3+, Tm3+, Dy3+, Sm3+, Pr3+, Nd3+, Er3+) in the ionic liquid bmpyr Tf2N (bmpyr = 1-n-butyl-1-methylpyrrolidinium) are presented. The luminescence quantum efficiencies, eta, and radiative lifetimes, tau(R), are determined for Eu3+(D-5(0)), Tm3+(D-1(2)), Dy3+(F-4(9/2)), Sm3+((4)G(5/2)), and Pr3+(P-3(0)) emission. The luminescence lifetimes in these systems are remarkably long compared to values typically reported for Ln(3+) complexes in solution, reflecting weak vibrational quenching. The 1.5 mu m emission corresponding to the Er3+ (I-4(13/2)-> I-4(15/2)) transition, for example, exhibits a lifetime of 77 mu s. The multiphonon relaxation rate constants are determined for 10 different Ln(3+) emitting states, and the trend in multiphonon relaxation is analyzed in terms of the energy gap law. The energy gap law does describe the general trend in multiphonon relaxation, but deviations from the trend are much larger than those normally observed for crystal systems. The parameters determined from the energy gap law analysis are consistent with those reported for crystalline hosts. Because Ln(3+) emission is known to be particularly sensitive to quenching by water in bmpyr Tf2N, the binding properties of water to Eu3+ in solutions of Eu(Tf2N)(3) in bmpyr Tf2N have been quantified. It is observed that water introduced into these systems binds quantitatively to Ln(3+). It is demonstrated that Eu(Tf2N)(3) can be used as a reasonable internal standard, both for monitoring the dryness of the solutions and for estimating the quantum efficiencies and radiative lifetimes for visible-emitting [Ln(Tf2N)(x)](3-x) complexes in bmpyr Tf2N.
