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.
