Directing the Mobility of Guest Molecules in Nanoporous Materials by Linearly Polarized Light

Advanced Science, Volume 13, Issue 8, 9 February 2026.
The polarization of light is introduced as a further parameter to dynamically and reversibly control the properties of a photoresponsive nanoporous material. It was used to control the mobility of the guest molecules in the pores of a metal–organic framework.

Bidirectional Photoadaptive Organic Heterojunction Synaptic Transistors for Accurate Image Recognition in Machine Vision Systems

Advanced Science, Volume 13, Issue 7, 3 February 2026.
Bidirectional photoadaptive organic synaptic phototransistors are developed using complementary n–n and n‐p heterojunctions. These devices enable intelligent in‐sensor processing, markedly enhancing image contrast and edge features under adverse lighting, and achieve a recognition accuracy of 97.4% within ten training cycles for machine vision ...

Optically Switchable Full‐Color Quantum Dots via Diarylethene Photoswitches for Smart Display and Security

SmartMat, Volume 7, Issue 1, February 2026.
An innovative photoswitchable system based on quantum dots and diarylethene enables reversible RGB photoluminescence switching. The system achieves over 90% photoluminescence quantum yield in the on state and a high on/off ratio of ~100. Efficient switching is driven by synergistic Förster resonance and triplet energy transfer, applicable for ...

Optochemical modulation of corneal cold nerve terminal impulse activity with a photochromic ion channel blocker

British Journal of Pharmacology, Volume 183, Issue 3, Page 545-559, February 2026.
Background and Purpose The functional organization of corneal cold nerve endings, critical structures in maintaining the ocular surface, remains poorly understood. Here, the photoisomerizable small‐molecule diethylamine‐azobenzene‐quaternary ammonium (DENAQ) was used to photomodulate activity of cold‐sensing nerve terminals in control and chronic tear ...
