- Аннотация: Chemical origin of solvents typically used for preparation of hybrid lead halide perovskites – dimethyl sulfoxide (DMSO), dimethylformamide (DMF) and gamma-butyrolactone (GBL) – strongly influences on the process of perovskite crystallization due to formation of intermediate adducts with different structures and morphology. The composition and crystal structures of the adducts depend on the coordination and binding ability of the solvents and the ratio of the precursors. New adducts of perovskite and GBL either with an unusual cluster structure, (MA)8(GBL)x[Pb18I44], or an adduct (MA)2(GBL)2Pb3I8 similar to those observed for DMF and DMSO are described for the first time. Complex equilibriums between chemical species existing in perovskite solutions is revealed by Raman spectroscopy. As a result, new features of the perovskite crystallization through intermediate adduct phases are discussed and effective perovskite deposition pathways are suggested.
