Hybrid organic–inorganic metal halide perovskites possess exceptional structural tunability, with three‐ (3D), two‐ (2D), one‐ (1D), and zero‐dimensional (0D) structures on the molecular level all possible. While remarkable progress has been realized in perovskite research in recent years, the focus has been mainly on 3D and 2D structures, with 1D and 0D structures significantly underexplored. The
杂化的有机-无机金属卤化物钙钛矿具有出色的结构可调性,在分子水平上具有三(3D),两(2D),一(1D)和零维(0D)结构。尽管近年来钙钛矿的研究取得了显着进展,但重点主要放在3D和2D结构上,而1D和0D结构的研究还很不足。报道了一系列具有一维和零维结构的低维有机溴化钙钛矿钙钛矿的合成与表征。使用相同的有机和无机组分,但在不同的比例和反应条件下,1D(C 4 N 2 H 14)SnBr 4和0D(C 4 N 2 H 14)Br)4 SnBr 6可以高产率制备。此外,实验和理论上研究了从1D到0D的光诱导结构转变,其中1D金属卤化物链的光解离,然后进行结构重组,导致形成了热力学更稳定的0D结构。
