1：Experimental Design and Method Selection:

The study involved synthesizing a Tb-MOF using hydrothermal methods, followed by structural characterization, gas adsorption measurements, and luminescence-based sensing experiments for solvents and metal ions. Theoretical models included crystal structure analysis and fluorescence quenching mechanisms.

2：Sample Selection and Data Sources:

The Tb-MOF was synthesized from Tb(OAc)3·6H2O and H3DBB ligand. Metal ion solutions (e.g., Fe3+, Cu2+) and organic solvents (e.g., acetone, isopropanol) were used as analytes.

3：List of Experimental Equipment and Materials:

Equipment included VarioEL elemental analyzer, NicoletAvatar 360 FT-IR spectrometer, Netzsch STA449 F3 thermogravimetric analyzer, SHIMADZU XRD-7000 X-ray diffractometer, Lingguang F97Pro fluorescence spectrophotometer, Edinburgh instruments FLS980 fluorescence spectrophotometer, ASAP 2020 surface area analyzer, and Bruker SMART APEX CCD diffractometer. Materials included Tb(OAc)3·6H2O, H3DBB, various solvents, and metal salts.

4：Experimental Procedures and Operational Workflow:

Synthesis was done via hydrothermal reaction at 140°C for 72 hours. Characterization involved elemental analysis, IR spectroscopy, TGA, XRD, fluorescence spectroscopy, and gas adsorption. Sensing experiments involved immersing Tb-MOF in solvents or ion solutions, ultrasonication, aging, and measuring fluorescence intensity.

5：Data Analysis Methods:

Data were analyzed using software like APEX-II and SHELXTL for crystal structure, and linear regression for quenching effects. Statistical methods included calculating detection limits and linear coefficients.
