The frequency responses of a langasite crystal microbalance （LCM） in liquid.phase were investigated. It was shown that the LCM possessed much stronger oscillating ability in liquid.phase than that of the commonly used quartz crystal microbalance （QCM）. The frequency shifts of the LCM to the changes in mass loading, as well as viscosity and density of the liquid.were measured. The LCM was applied to monitor the adsorption process of an ionic liquid.film to ethanol vapor.

Polythiophene (PTh) was prepared by the direct electrochemical synthesis in an ionic liquid.([BMIM]PF6) containing 0.1 mol/L thiophene by cyclic voltammetry, constant potential and constant current techniques. It is found that smooth and bluegreen PTh films can be obtained at a potential of ca. +1.75 V ( vs. Ag/AgCl ) or a current of ca. 1.5 mA cm-2 in the ionic liquid.

Acylation reaction of anthracene with oxalyl chloride in the presence of [Emim]C1-A1C13 ionic liquid.has been investigated. Pure 1,2-aceanthryenedione, which is used as intermediate of functional aromatic polymer material, was obtained by recrystalling the reaction mixture with aether and was determined by GC/MS, 1HNMR and FTIR analysis. The influences of various parameters, such as the contents of AlCl3 in [Emim]C1-A1C13, the amount of acylation agent, amount of [Emim]C1-A1C13, reaction temperature and reaction time were investigated. The optimum conditions were as follows: the molar fraction of A1C13 in ionic liquid.[x(AlCl3)] being 0.67 , molar ratio of ionic liquid.to anthracene being 2:1 , molar ratio of oxalyl chloride to anthracene being 2:1, reaction temperature being 40℃ and reaction time being 6h. Under above conditions, the yield and selectivity of 1,2-aceanthrylenedione can reach 91.5% and 98.3% respectively. Further more, [Emim]C1-A1C13 ionic liquid. compared with metal halides such as AlCl3, was found to catalyze the reaction as a novel environmental friendly catalyst and solvent and can be reused.
