Designing Dual-State and Aggregation-Induced Emissive Luminogens from Lignocellulosic Biosourced Molecules

open access: yesMolecules
Utilizing lignocellulosic biosourced platforms, we synthesized novel cyanostilbene (CS) derivatives featuring the 3,4-dimethoxyphenyl moiety. These derivatives were investigated for their emission properties in both solution and solid states.

MIL‐88B‐NH2(Fe)‐Based Fiber‐Reinforced Polymer Electrolytes for Li‐Metal Batteries

open access: yesSmall Structures, Volume 7, Issue 4, April 2026.
MIL‐88B‐NH2(Fe) with open metal sites immobilizes anions and promotes salt dissociation; combined with fiber‐induced crystallinity reduction, this raises ionic conductivity and Li+ transference number, homogenizes Li+ flux, and lowers polarization for stable cycling.
