Lanthanide Functionalized Hydrogen-bonded Organic Framework Hybrid Materials: Luminescence Responsive Sensing, Intelligent Applications and Biomimetic Design

Abstract

As a distinct category of crystalline porous materials, hydrogen-bonded organic frameworks (HOFs) are assembled from organic building blocks through H-bonding and other weak intermolecular interactions, which position HOFs as a versatile platform for investigating multifunctional porous materials. Aromatic subunits existing in the majority of HOF linkers are responsible for the luminescence exhibited by HOFs upon ultraviolet excitation mostly in nature. Recently, there has been a surge of attention in utilizing luminescent functionalized HOFs for luminescence responsive sensing due to their strong fluorescence and phosphorescence emission, versatile postsynthetic functionalization property, great solution processing performance, outstanding luminescent stability and specific recognition ability, and excellent biocompatibility.
