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.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
