Main group halogenido metalates, especially lead halide perovskites, are under intense investigation for various semiconductor applications. We want to expand the chemistry of these materials in two directions, which have been under-explored until now. In the first project we want to apply the principles of high entropy materials to the synthesis of halogenido metalates. Here, one crystallographic position is statistically occupied by an equimolar amount of five or more different metal atoms. We expect this approach to yield materials with improved or entirely new properties. In the second project we want to synthesize ordered multinary halogenido metalates featuring group 13/15 or 14/15 elements. Preliminary works in this directions show that new materials can be obtained which show properties that strongly diverge from those of the simple monometallic metalates.

主要基团卤化金属酸盐，特别是卤化铅钙钛矿，在各种半导体领域的应用正受到广泛的研究。我们想在两个方向上扩展这些材料的化学性质，这两个方向到目前为止还没有得到充分的探索。在第一个项目中，我们希望将高熵材料的原理应用于卤素金属酸盐的合成。在这里，一个晶体位置在统计学上被等摩尔数量的五个或更多不同的金属原子所占据。我们期望这种方法能产生具有改进或全新性能的材料。在第二个项目中，我们想合成具有13/15或14/15族元素的有序多卤代金属酸盐。在这个方向上的初步工作表明，可以获得与简单的单金属金属酸盐具有强烈不同性质的新材料。
