Deciphering Small Molecule Diffusion Parameters Across Light Responsive Polymersome Membranes

Advanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
Light‐responsive polymersomes bearing donor–acceptor Stenhouse adducts (DASAs) enable programmable control over small‐molecule transport across synthetic membranes. By systematically varying DASA density, an optimal functionalization regime is identified that maximizes light‐gated permeability.

Mechanochromism of Glassy Polymers Enabled by a Loop‐Forming Supramolecular Mechanophore

Advanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
The supramolecular mechanophore LOOP is covalently introduced into glassy polymers, capable of reporting force‐induced pre‐failure damage and local fracture events in polymer glasses. Under different mechanical deformation modes, including grinding, tensile stretching, and scratching, LOOP probes irreversible events in polymer glasses through a ...

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

Advanced Materials Interfaces, Volume 13, Issue 10, 19 May 2026.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Reprogrammable All‐Photonic Molecular Logic With Ln3+ Luminescent Hybrids in Solid State

Laser &Photonics Reviews, Volume 20, Issue 9, 6 May 2026.
Mario P. de‐Saralegui et al. report an Eu3⁺/Tb3⁺‐doped organic–inorganic hybrid material that enables multiple reprogrammable logic operations using only physical stimuli. Additionally, this solid‐state, all‐photonic platform represents the first example in the literature performing reversible Feynman logic operations, marking a major step toward ...

Mechanochemical Activation of Spiropyran in PMMA ‐ A Hybrid Quantum Chemical/Atomistic/Coarse‐Grained Approach

Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.
A quantum mechanically informed hybrid coarse‐grained/atomistic spiropyran‐doped PMMA model was developed to study mechanophore activation under tensile deformation. The model provides novel insights into activation mechanisms, reproduces realistic onset strains and demonstrates higher activation rates in larger systems with longer polymer chains ...
