“…Oxygen has been shown to alter strongly the properties of is heated at 310 K under a flow of helium such as to remove any traces of adsorbed oxygen before the temperature is several charge-transfer salts such as TTF-TCNQ and (w 4 DTP)-TCNQ. 39 In the latter two compounds, the influence of oxygen lowered and (ii) direct cooling of the sample. The differences in the EPR signal are obvious and consist mainly in a strong has been observed to result in a steep increase of the susceptibility near 48 K. Partial pressures as low as 0.005 Torr (P tot line shape modification with the appearance of one or several broad components when oxygen is present in the sample.…”

Unprecedented magnetic behaviour in lanthanide-based ionic liquids

Ionic liquids containing lanthanide halide anions give the opportunity to investigate magnetic behaviour in non-ordered systems. Reported herein is the synthesis and characterization of ionic liquids containing a series of lanthanide halide anions, with the resulting materials displaying unusual behaviour below 50 K. Specifically, the ionic liquid structural glass formation appears to drive magnetic behaviour due to cluster formation of the anions during rapid cooling. This system presents a possible probe to study the dynamics of glass forming materials.

The EPR linewidth of triphenylmethylarsonium (TCNQ)2 was measured as a function of crystal orientation at room temperature. The anisotropy is reproduced by calculating the static dipole–dipole interaction in the dense triplet exciton system and including the modulation by the exchange coupling between excitons. The exchange frequency is found to be ωe=6.7×109 s−1. A discussion of the effects of adsorbed molecular oxygen is also included.
