Cage‐Ligand Strategy for the Construction of Zr₄(embonate)₆–Based MOFs with Third‐Order Nonlinear‐Optical Properties

Abstract

Comprehensive Summary Herein, we demonstrate a very useful strategy to construct cage‐based metal‐organic frameworks (MOFs) with third‐order nonlinear‐optical properties. More specifically, by employing the Zr4L6 (L = embonate) cages to assembly with N‐contained ligands and Mn2+/Zn2+ ions, four Zr4L6‐cage‐based MOFs have been synthesized and structurally characterized. Among them, a 3D framework with strong aromatic π − π stacking force exhibits a good optical limiting effect.

Tuning Energy Transfer in Metal‐Organic Frameworks for Fluorescence Turn‐on Sensing of Hg(II) Ions†

“…Owing to their excellent crystallinity, high surface areas, and tunable pore structure and functional properties, MOFs have been demonstrated to be useful in a broad range of research areas, such as molecular adsorption and separation, [ 4‐10 ] energy devices, [ 11‐15 ] drug delivery, [ 16‐20 ] sensing, [ 21‐26 ] and so on. Luminescent MOFs, [ 27‐44 ] a subclass of functional MOFs, [ 45 ] which are primarily constructed by reticulating luminescent metal ions or/and organic linkers/guests into the frameworks, have been well applied for diversifying the potential optoelectronic applications of MOFs. For example, Li et al .…”

Cationic metal–organic framework with charge separation effect as a high output triboelectric nanogenerator material for self-powered anticorrosion

“…Accordingly, ionic MOFs are strong candidate materials for frictional power generation. [20][21][22][23][24][25] The intrinsic charge dispersion in ionic MOF materials provides rich molecular or electronic structures that promote the acquisition/loss of charge and enable the charge-separation state and consequent electronic effect. These characteristics effectively reduce the work function of ionic MOFs.…”
