Near-infrared emitters based on post-synthetic modified Ln(3+)-IRMOF-3

abstract

Post-synthetic covalent modification of the metal-organic framework IRMOF-3 amino group with pentane-2,4-dione and 3-(2-hydroxyphenyl)-3-oxopropanal followed by the coordination of Nd3+/Y3+ allows the design of near-infrared light-emitting materials.
