Within this project, we aim at the optimization and development of sustainable, low-temperature approaches to crystalline chalcogenidometalates by ionothermal synthesis, and at the deep understanding of the corresponding processes. Our target compounds and respective synthetic strategies are: 1) ternary nano-structured, crystalline chalcogenidometalate materials that will be synthesized by uncommon precursor combinations, and 2) complex and heavy metal chalcogenidometalate materials that will be accessed by employment of ionic liquids as non-innocent reaction media. The target compounds have been carefully selected according to our experiences and according to new collaborations that were installed during the previous funding period. The compositions can be generalized by the following formula: (Cat)q[(Mt,c,a,hx)TyEz(R)j][An]p (Cat = alkali metal, (element-)organic or complex cation; Mt = transition metal; Mc = pentel metal within complex cation: Sb, Bi; Ma = triel metal within complex anion: Ga, In; Mh = heavy metal: Cd, In, Sn, Sb, Hg, Pb, Bi; T = Ge, Sn; E = S, Se, Te; R = organic group; An = (pseudo-)halide or complex anion). By variation of the composition, we will address the products' specific opto-electronic and thermoelectric properties that are analysed by a diversity of experimental and computational methods by ourselves or in collaborations within the framework of SPP 1708.

在该项目中，我们旨在优化和开发可持续的，低温的方法，通过离子热合成，以及对相应过程的深刻理解。我们的目标化合物和各自的合成策略是：1）三元纳米结构化的，结晶的辣椒粉化含量材料，这些材料将通过不常见的前体组合合成，而2）复杂的和重的金属chalcogenidementate材料将通过使用离子液体作为非企业液体液体的使用，这些材料将通过非企业液体的使用来访问。根据我们的经验以及在上一期融资期间安装的新合作，已仔细选择了目标化合物。组成可以通过以下公式推广：（CAT）Q [（MT，C，A，HX）Tyez（r）J] [AN] P（Cat = Alkali Metal，（元素）有机或复杂阳离子； Mt =过渡金属; MC = MC = Pentel Metal; MC = Pentel Metal; Ma pb，t = ge，e = s，r =有机体;通过组成的变化，我们将解决产品的特定光电和热电特性，这些特性通过我们自己或在SPP 1708框架内的多种实验和计算方法进行分析。
