有机金属卤化物钙钛矿是近年来发展起来的一类具有广泛应用前景的功能材料。特殊的结构可调性使这些材料在分子水平上具有三维（3D），二维（2D），一维（1D）和零维（OD）结构。近年来，钙钛矿的研究取得了显著进展，主要集中在3D和2D结构上，但对低维1D和OD结构的研究明显不足。在这里，我们提供我们的观点在低维有机金属卤化物钙钛矿最令人兴奋的发展。由于强的量子限制和位置隔离，1D和OD钙钛矿表现出与3D和2D钙钛矿显著不同的显著和有用的性质。令人兴奋的是，最近的发展不仅在于具体的成就，而且还在于这些材料在材料设计的新范式方面所代表的内容。
Organometal halide perovskites have recently emerged as a highly promising class of functional materials for a variety of applications. The exceptional structural tunability enables these materials to possess three- (3D), two- (2D), one- (1D), and zero-dimensional (OD) structures at the molecular level. Remarkable progress has been realized in the research of perovskites in recent years, focusing mainly on 3D and 2D structures but leaving low dimensional 1D and OD structures significantly underexplored. Here we offer our perspective on the most exciting developments in the low-dimensional organometal halide perovskites. Due to the strong quantum confinement and site isolation, 1D and OD perovskites exhibit remarkable and useful properties that are significantly different from those of 3D and 2D perovskites. The excitement about the recent developments lies not only in the specific achievements but also in what these materials represent in terms of a new paradigm in materials design.
