Ionic liquids as crystallisation media for inorganic materials

Controlled Synthesis of Polyions of Heavy Main-Group Elements in Ionic Liquids

“…In addition, the concentration of the different halogenidometalate species can be tuned by temperature [100], mole fraction of employed MX 3 [5], and by adding additional free X − anions [5100]. The latter has been utilized by Ruck et al to overcome hindered crystallization of products by adding small amounts of NaCl after completion of the reaction to increase the mole fraction of [AlCl 4 ] − [23,26,101]. …”

“…Owing to the distinctive physicochemical properties of ILs (wide liquidus range, high redox and thermal stability, negligible vapor pressure, and tunable polarity) and their advantages over organic solvents, classic melts, or solid state reactions, their applications include separation techniques [7,8,9], lubrication [10], electrodeposition [11], acting as electrolytes in photovoltaic devices (e.g., solar cells) [12,13,14], catalysis for clean technology [15,16,17,18], polymerization processes [19], crystal engineering of a wide range of inorganic substances [20,21,22,23,24,25], and syntheses of new inorganic materials in general [23,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51]. Recently, several comprehensive reviews on syntheses of inorganic compounds in ILs have been published by Taubert [52], Feldmann [28], Dehnen [51], Janiak [42,53], Scrosati and Passerini [48], Morris [54], Mudring [55], Prechtl [56], Zhu [57], Dai [58], and Ruck [23,27,59] among others.…”

Intrinsic Nature of Interfacial Interactions between Ionic Liquids and Rutile TiO2 Single Crystal Surfaces Studied by in Situ Contact Angle Measurement in a Vacuum

“…If we come to be able to examine the wettability of ILs on a solid surface prepared in vacuum, it would provide some insight into the intrinsic interfacial interactions, some of which will be important for the various kinds of applications where the IL/solid interface plays an important role, for examples in electrochemistry 16,17 , analytical chemistry 18 , catalyst 19-21 , nano-particle synthesis 22,23 , and crystal growth.

Bis((dialkylamino)alkylselenolato)metal complexes as precursors for microwave-assisted synthesis of semiconductor metal selenide nanoparticles of zinc and cadmium in the ionic liquid [BMIm][ BF4]

“…Due to their unique physicochemical properties ionic liquids, especially room temperature ionic liquids like 1-butyl-3-methylimidazolium tetrafluoridoborate, [BMIm] [BF 4 ], have recently received attention as media for the synthesis of different types of nanoparticles [16][17][18][19][20][21] and inorganic materials [22,23] such as metal oxides including ZnO [24] or CuO semiconductor nanoparticles [25,26], metal chalcogenides [27,28], polynuclear metal complexes [29][30][31]. Among others, the properties of ILs include a high dielectric constant, polarity, thermal stability and a negligible vapor pressure.…”
