Functional Construction of Dual‐Emitting 4‐Aminonaphthalimide Encapsulated Lanthanide MOFs Composite for Ratiometric Temperature Sensing

Abstract Considering size effect and functionalized pore interaction dyes guests and MOFs hosts, 4‐aminonaphthalimide was successfully introduced into the pore of LnMOF for the first time and constructed 4‐ANA⊂LnMOF luminescent composites with excellent dual‐emission properties. A series of temperature‐dependent luminescence test results show that 4‐ANA⊂Gd4L3 can be used as a reversible ratiometric luminescent temperature sensor. The functional construction method provides ideas for the development of clear purpose novel dual‐emission dye⊂LnMOF ratiometric luminescent sensors.
