Layered Porous Perovskites: New Building Blocks for Porous Materials

Abstract:
The synthesis of microporous hybrid solids like metal–organic frameworks involves connecting different molecular units like bridging organic ligands and metal building groups. Through this method, long-range communication between metal centers, a hallmark of many conductive or magnetic properties, can be challenging to install. We are investigating a different approach. We start with dense materials with known electromagnetic properties, and design synthetic routes to make them porous. In this talk, I will focus on our efforts to engineer crystalline microporosity in metal-halide perovskites. We demonstrate that this porosity allows for permanent encapsulation of electronically active molecules inside the framework, post-synthetic modification of the perovskite layer, and even stabilization of previously unknown perovskite phases. We also show preliminary data for synthesizing porous variants of ferromagnetic perovskites.
