This technology introduces porous, anisotropic metal–organic frameworks (MOFs) with magnetic nanoparticles attached on the surface, enabling precise spatial orientation using external magnetic fields. The magnetized MOFs can incorporate optical or fluorescent dyes, preserving their functional properties such as dichroism and fluorescence. This platform enables the development of opto-magnetic devices for sensing, authentication, pollutant capture, and light-based switching systems.
- Optical and magnetic field sensors
- Anti-counterfeiting and document authentication
- Removal of hazardous organic pollutants
- Polarized light detection and switching
- Magnetically responsive display technologies.
- Integrated optical and magnetic responsiveness in a single crystalline material
- Tunable optical output (color, brightness, fluorescence) via orientation and polarization
- Demonstrated stability across multiple MOF compositions and dye types

Dyes that were embedded: sodium resorufin, methyl orange, lithium 7,7,8,8-tetracyanoquinodimethane, sodium fluorescein, sodium 5-aminofluorescein, and fluorescein isothiocyanate isomer I.
These materials kept their properties in the MOFs.
