摘要
Two-dimensional(2D)organic–inorganic halide perovskites present remarkable stability and diversity and are promising alternatives to their three-dimensional(3D)counterparts.The 2D halide perovskite[(HO)(CH_(2))_(2)NH_(3)]_(2)PbI_(4)is regarded as a superior moisture-stabile“smooth”perovskite because of distinct hydrogen-bond networks that connect adjacent organic–inorganic layers.
