To develop ML models that can directly guide future experimental efforts, it is essential to first understand the behavior and potential limitations of various levels of theory when predicting MOF electronic structure properties. As such, we begin by comparing the DFT-predicted band gaps for 10,720 structures in the QMOF Database with the PBE (GGA: 0% HF exchange), HLE17 (meta-GGA: 0% HF exchange), HSE06 * (screened hybrid: 10% HF exchange at small interelectronic distances decreasing to zero at large distance), and HSE06 (screened hybrid: 25% HF exchange at small interelectronic distances decreasing to zero at large distance) functionals.
