Pressure-responsive Fluorescent Behavior and Sensing Performance of Anthracene/Montmorillonite Composites
摘要
Abstract
Visualization-enabled monitoring under extreme pressure requires luminescent systems that can directly convert pressure variations into a readable and quantifiable spectral shift or color change.Organic luminophores are intrinsically sensitive to molecular packing and the local microenvironment,offering strong potential for pressure-in-duced color tuning,yet their high-pressure applications are often limited by solid-state aggregation-caused quenching and insufficient stability.Here,anthracene(An)was employed as the emissive unit and confined via an interlayer-intercalation strategy within organo-modified montmorillonite to form An-based composites.As the intercalation ratio increases from 2∶1 to 1∶12,the(001)reflection continuously shifts to lower angles with an expanded basal spacing,indicating effective intercalation and homogeneous dispersion of An,accompanied by a pronounced enhancement in solid-state emission;the confined and hydrophobic interlayer environment further prolongs the emission lifetime.In situ diamond anvil cell measurements show that the 1∶12 composite exhibits a continuous red shift of the emission maximum with a visible color evolution from bluish-violet to yellow upon compression.A strong linear relationship be-tween peak position and pressure is obtained over 1.60-10.1 GPa(R2=0.996),with partial reversibility during de-compression.These results demonstrate that interlayer confinement can simultaneously unlock the piezochromic ad-vantages of organic emitters while suppressing solid-state quenching,providing an effective route toward visualiza-tion-enabled fluorescent manometry materials.关键词
