Synthesis and Conductive Performance of Temperature Control-type Ionic Liquid Based on Keggin Polyoxometalate

摘要

A temperature control-type ionic liquid based on ternary Keggin polyoxometalate, [PyPS]_4PW_(11)O_(40) has been synthesized and characterized. It is solid state at room tempareture and it shows a phase transformation below 100°C. The results indicate that this compound possesses layered type structure. Its conductive performance is investigated. Its conductivity is as high as 6.20 × 10~(_3) S·-cm~(-1) at 120°C.
