Amino-decorated lanthanide( iii ) organic extended frameworks for multi-color luminescence and fluorescence sensing

Four luminescent lanthanide–organic frameworks (Ln = Eu ³⁺ , Tb ³⁺ , Sm ³⁺ and Dy ³⁺ ), isostructural to MOF-LIC-1(Gd), are assembled. Multiple colors are obtained for the system and white-light emission is realized by the single component Sm( iii ) framework. Most interestingly, Eu-MOF performs highly selective and sensitive luminescence sensing of Al ³⁺ .
