2D all-organic perovskites refine flexible electronics

<正>Recent years have witnessed a paradigm shift with the advent of perovskites,a class of materials with a distinct CaTiO3-type crystalline structure that show remarkable promise across a wide array of applications,including photovoltaics,photodetectors,lighting,lasers,and so forth.Among them,the development of two-dimensional （2D） perovskites has garnered significant attention due to their tunable structures （mainly Dion-Jacobson and Ruddlesden-Popper structures） and enhanced stability in comparison with their 3D counterparts [1].
