Discerning two-dimensional metal halide perovskite moieties using solid-state NMR fingerprints.

ABSTRACT: Low-dimensional perovskites hold great promise for optoelectronic applications, spanning from photovoltaics to photonic platforms. The electronic properties of these soft hybrid semiconductors critically depend on their crystal structure, and the ability to clearly discern the connectivity of the inorganic component and the organic molecular packing is crucial to foster the development of improved materials. In this work, we apply solid-state NMR spectroscopy (ssNMR) to compare two perovskites with different structural motifs: the flat 〈100〉-oriented Ruddlesden-Popper (BA)₂PbI₄ and the corrugated 〈110〉-oriented Dion-Jacobson phase (EDBE)PbI₄, which are flat and corrugated layered perovskites, respectively. Combining experimental characterizations under stat
