| With growing concern over the environmental impact and health hazards of traditional volatile organic solvents, researchers continue to search for greener alternatives. Room-temperature ionic liquids (RTILs) are becoming viable"green"substitutes for organic solvents with incomparable characteristics, such as negligible vapor pressure, low melting points, wide range of liquidus temperatures, low toxicity, nonflammability, large electrochemical window, good solvents for many organic and inorganic materials. As a new promising method for preparing materials following hydrothermal/ solvothermal method, ionothermal synthesis has been attracting more and more study since it was developed by Morris et al in 2004.In this paper, the ionothermal synthesis of aluminophosphate molecular sieves, indium hydroxide and indium sulfide has been studied. A novel hexagonal fluorinated aluminophosphate molecular sieve has been synthesized ionothermally in 1-ethyl-3-methylimidazolium bromide RTIL with a suitable volume of HF. Then the ionothermal method was used for the preparation of indium hydroxide and indium sulfide for the first time. Products with different morphologies were obtained by adjusting different kind of RTILs (including special eutectic mixture), reaction precursors and the reaction time. Due to the presence of amine, crystal large particles were obtained. The products were characterized by XRD, SEM, TEM, FT-IR and PL and we investigated the morphology variations of structures with different conditions. This shows that RTILs act as both solvent and template provider. In addition, the amine has a significant influence on reaction process of indium sulfide and the corresponding products have strong optical properties.
