Mechanochromic Organic Materials: Molecular Mechanisms and Multidimensional Applications

open access: yesAdvanced Physics Research, EarlyView.
Mechanochromic (MC) organic materials change color in response to mechanical force. This review elucidates the molecular mechanisms (e.g., aggregation‐induced emission, AIE) and explores their multidimensional applications in sensors, anti‐counterfeiting, biomedical devices, and structural health monitoring, providing a roadmap for future smart ...

Aromatic Diester Anolytes for Nonaqueous Redox Flow Batteries

open access: yesBatteries &Supercaps, EarlyView.
Owing to their extended π‐conjugation 2,2′‐bipyridyl aromatic diesters are stable in singly‐ and doubly‐reduced states. In a redox flow battery a high battery voltage of 2.82 V can be realized and a capacity a capacity retention of 99.5% per cycle for 260 cycles.

On‐Liquid Surface Synthesis of Crystalline 2D Polyimine Thin Films

open access: yesChemistryEurope, EarlyView.
This work demonstrates the on‐liquid surface synthesis of crystalline 2D polyimine films by leveraging a fluorinated surfactant and a binary solvent mixture of DMAc‐H2O. In situ grazing incidence X‐ray scattering reveals stepwise monomer adsorption, preorganization, and polymerization, accompanied by lattice expansion from 3.4 to 5.3 nm.
