Large amount of toluene and carbon tetrachloride can be absorbed into 1-dimensional tunnels in copper(II) trans-1,4-cyclohexanedicarboxylate Cu2(OOC-C6H10-COO) under the saturated vapor pressure at room temperature. The absorbed toluene and carbon tetrachloride can be desorbed easily by evacuation above room temperature, and the absorption/desorption is completely reversible. The absorption/desorption phenomena were studied for the empty, partly and fully toluene and carbon tetrachloride absorbed samples by adiabatic calorimetry between 13K and 300K and by powder X-ray diffractiometry with high-energy synchrotron radiation at SPring-8 of JASRI. The first-order phase transition was observed in the empty sample. The partly toluene-absorbed samples showed smaller heat capacity anomaly at higher temperatures than the empty sample. On the other hand, the partly carbon tetrachloride-absorbed samples showed smaller heat capacity anomaly at lower temperatures than the empty sample. The difference in the two cases was discussed on the basis of structural and thermal data.

Thermal conductivity via electron and spin degrees of freedom has been a valuable tool to study superconducting properties of high-Tc cuprates and quantum fluctuation of one-dimensional spin liquids. It turned out that presence of metallic quasiparticles is necessary for the superconducting phase transition for the high-Tc cuprates. It is also demonstrated that spin excitations carry a large amount of heat in the one-dimensional quantum magnet, indicating their excellent spatial coherence like phonons and electrons in metals. The thermal conductivity measurement will be useful more generally in studying exotic properties of strongly-correlated electron systems.
