Electrostatic potential (ESP) plays an essential role in studying interactions among molecules. Developing probe materials capable of selectively detecting analytes by aligning their molecular ESP with the electrostatic interaction host material is critically important for identifying analogous analytes; however, relevant research extremely lacking. In this work, we synthesized a luminescent metal-organic framework (LMOF, Cd-DBDP) featuring negative pore environments achieved incorporating numerous electronegative oxygen atoms and N-containing aromatic rings from organic linkers. The distributions Cd-DBDP RNA-related nucleotides were calculated employed to predict sensing results. Fluorescence tests demonstrated that represents first example MOF-based sensor guanosine diphosphate (GDP) sensing, experimental observations highly consistent theoretical prediction. mechanism GDP was thoroughly studied through Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy/energy-dispersive (SEM/EDS), X-ray photoelectron (XPS), calculations. These findings provide valuable insights into understanding interplay between distribution condition This study offers guide future sensory provides effective means design synthesis efficient MOFs, lending solid groundwork further exploration field.
