Abstract
We demonstrate that the nanosize effect of a host matrix appears to affect the emission properties of guest dye molecules encapsulated in the pores of a metal–organic framework as a host (dye@MOF).
Highlights
Over the last few decades, several different strategies have been developed to improve the emissive properties of organic molecules in the solid state.[1,2,3,4] Among them, the encapsulation of emissive organic dye molecules in a porous host matrix is an attractive method
We demonstrate that the nanosize effect appears to affect the properties of dye molecules encapsulated in the pores of a metal–organic framework
We investigated if the presence of the competing ligand in the precursor solution was the key to controlling the crystal shape in terms of equilibrium reactions between metal ion and ligand. 1-MIm was used as a competing ligand in the reaction system
Summary
Over the last few decades, several different strategies have been developed to improve the emissive properties of organic molecules in the solid state.[1,2,3,4] Among them, the encapsulation of emissive organic dye molecules in a porous host matrix is an attractive method. Host–guest interactions between the host matrix and guest emissive molecules are strongly affected by the host nanostructure, such as the crystal size, pore size/shape and framework components
