With the escalating prevalence of terrorism and global environmental pollution, nitroaromatic compounds (NACs) have increasingly come into focus as primary culprit. To counter these challenges, it is imperative to develop simple efficient methods for detecting NACs. Considering electron-deficient structure NAC molecules, this paper constructed a novel three-dimensional In-MOF with permanent porosity using electron-rich organic molecules 4'-[1,2,2-tris(3',5'-dicarboxy[1,1'-biphenyl]-4-yl)ethenyl]-[1,1'-biphenyl]-3,5-dicarboxylic acid (H

Abstract Advances in energy‐efficient lighting and display technologies demand innovative materials with tailored broad‐spectrum emission properties. Hybrid aggregation‐induced metal‐organic frameworks (AIE‐MOFs) offer a promising avenue, combining unique characteristics of organic inorganic components to yield enhanced luminescence efficiency robust material stability. The study introduces spectrum D (donor)‐A (acceptor) type AIE‐active ligands into MOFs, enabling tunable across the visible spectrum, thus underscoring versatility these hybridized MOF materials. properties AIE‐MOFs are further harnessed by integrating them polymer matrices, resulting high‐performance electrospun fibers emission. A significant achievement involves fabrication Janus‐type white light‐emitting AIE‐MOF fiber composites via side‐by‐side electrospinning, accomplishing high quantum 58%, which doubled performance homogeneous fibers. Complementing experimental findings, micro‐Raman nano‐Fourier transform infrared spectroscopy employed as local spectroscopic probes, affording deeper understanding mechanisms contributing enhance light In understanding, this presents an unconventional implementation hybrid structures for It significantly improves sources optoelectronics, charting direction future research emergent field.

The monomer emission property of the tetraphenylethene (TPE) derivative is rarely reported, and its photoluminescence (PL) mechanism related to supramolecular self-assembly needs further in-depth research. Two long alkyl chain modified derivatives, TPE (TPE-C10) pyrene (Pyrene-C10), are designed synthesized, which possess similar assembly behavior but exhibit different PL properties. TPE-C10 not only forms morphologies with also emits aggregation-induced (AIE). Moreover, polymer microspheres containing Pyrene-C10 prepared, can dissolve or swell in organic solvents. changed binding effect chains achieves luminescence transformation from AIE emission. This work hopefully enrich luminescent materials based on provide a new method for studies about luminescence.
