Abstract

This study is devoted to investigating the stability of metal-organic framework (MOF)-hybrid perovskites consisting of CH₃NH₃PbI₃ (MAPbI₃) and UiO-66 without a functional group and UiO-66 with different COOH, NH₂,and F functional groups under external influences including heat, light, and humidity. By conducting crystallinity, optical, and X-ray photoelectron spectra (XPS) measurements after long-term aging, all of the prepared MAPbI3@UiO-66 nanocomposites (with pristine UiO-66 or UiO-66 with additional functional groups) were stable to light soaking and a relative humidity (RH) of 50%. Moreover, the UiO-66 and UiO-66-(F)₄ hybrid perovskite films possessed a higher heat tolerance than the other two UiO-66 with the additional functional groups of NH₂ and COOH. Tthe MAPbI3@UiO-66-(F)₄ delivered the highest stability and improved optical properties after aging. This study provides a deeper understanding of the impact of the structure of hybrid MOFs on the stability of the composite films.
