1：Experimental Design and Method Selection:

The study involved preparing MOF inks by mixing MOFs with methacrylate-terminated perfluoropolyether (PFPE) in solvents, followed by UV curing. Various processing techniques like spray coating, pen writing, stencil printing, and moulding were used to form structures.

2：Sample Selection and Data Sources:

MOFs such as HKUST-1, MIL-101(Cr), ZIF-67, ZIF-8, MOF-74(Ni), Zn2(bdc)2(dpNDI) (MOFchemo), and Tb

3：99Eu01(hfa)3(dpbp) (MOFthermo) were synthesized and used. List of Experimental Equipment and Materials:

Equipment included Zetasizer Nano for DLS, Bruker D8 advance diffractometer for XRPD, ThermoFisher Scientific Nicolet 6700 FT-IR spectrometer, Viscosity Meter SV-10, Hitachi High-Technologies Cold FE-SEM, JOEL JEM-2200FS HRTEM, BELSORP-max for nitrogen sorption, Varian Cary Eclipse for fluorescence spectra, Agilent 400 MHz spectrometer for FT-NMR. Materials included PFPE (Fluorolink MD 700), photoinitiator Darocur 1173, and various chemicals for MOF synthesis.

4：Experimental Procedures and Operational Workflow:

MOF inks were prepared by dispersing MOFs in ethanol or dichloromethane with PFPE, sonicating, and then applying via spray coating, pen writing, stencil printing, or moulding, followed by UV curing. Sensing tests involved immersing coated devices in solvents or aqueous solutions and monitoring luminescence.

5：Data Analysis Methods:

Data were analyzed using BET method for surface area, contact angle measurements, SEM, TEM, EDS, XRPD, and fluorescence spectroscopy.
