The rational development of solid-state reactions is one of the objectives of the green chemistry movement. Following our reports on a mechanosynthesis as a powerful method for environmentally friendly, clean and energy-efficient synthesis, in 2015 we reported an efficient room-temperature mechanosynthesis of the hybrid organic– inorganic perovskite MAPbI3 with a well-defned structure and composition.1
Furthermore, our research Focus extends to compositional engineering in metal halide perovskites (MHPs). Harnessing the power of mechanical forces, we have devised an efficient and straightforward method for solvent-free composition engineering. The solid-state chemical reactions emerged as an efficient and simple method for the solvent-free composition engineering of various high-purity monocation and multicomponent 3D lead and lead-free halide perovskites in a relatively short time (>30 min) with the high reproductibility. Notably, this approach also provides an efficient one-step general method for incorporating poorly soluble salts into multicomponent perovskite crystal lattices.2
