Small‐Molecule Kinase Inhibitors Modulating Circadian Rhythms

open access: yesMedicinal Research Reviews, Volume 46, Issue 6, Page 1735-1752, November 2026.
ABSTRACT The circadian clock mechanism generates 24‐h rhythms crucial for regulating various physiological processes, and its dysregulation has been implicated in numerous diseases. In cells, the circadian clock operates through a transcriptional‐translational feedback loop, where phosphorylation plays a pivotal role in maintaining accurate circadian ...

A de‐novo Approach Towards Divergent [3+2π/σ] Photocycloadditions of Nitrones via Assembly‐Controlled Kinetic Electron Transfer Gating

open access: yesAngewandte Chemie, Volume 138, Issue 43, 19 October 2026.
A metal‐free photocatalytic platform converts nitrones into 4‐isoxazolines and oxa–aza–bicycloheptanes through divergent [3+2π/σ] cycloadditions. Assembly‐controlled kinetic electron transfer gating dictates substrate activation, enabling selective reactivity beyond thermodynamic expectations.

Proton Activated Photoisomerization of Dibenzofulvene Molecular Actuators

open access: yes, 2018
Our group has shown that dibenzofulvene rotors behave as an efficient class of light driven molecular actuators that give a range of photoisomerization quantum yields from 0.04 to 0.5 depend upon the substituents.

Directed Buckling of Molded LCE Sheets for Haptic Interfaces

open access: yesChemSystemsChem, Volume 8, Issue 6, November 2026.
Liquid crystalline elastomers (LCEs) can undergo reversible deformations in response to heat or light. This theoretical and computational work shows how through molding and selective illumination, LCE devices can be made to exhibit phototropic or photophobic buckling from a monolithic structure, allowing the LCE to serve as a rewriteable haptic ...

TADF‐Active Tetrazole Luminophores for Visible‐Light Functionalization of Nanoparticles and Surfaces

open access: yesAngewandte Chemie, Volume 138, Issue 43, 19 October 2026.
A series of tetrazoles are reported that undergo 1,3‐dipolar cycloadditions with alkene and alkyne substrates, generating (dihydro)pyrazole products that exhibit thermally activated delayed fluorescence (TADF). The “photo‐click” reactivity of these tetrazoles is leveraged to functionalize nanoparticles and surfaces with TADF‐active chromophores ...

Suppression effect and coupled two-time motion of the photoisomerization in the crosslinking polymer system

open access: yes, 2017
The photoisomerization of the crosslinked and uncrosslinked polymer-pair with azo linkages was studied by the photoinduced birefringence. The photoisomerization of azo chromophores could be controlled by crosslinking process.

Rapid Access to Photoswitchable RNA Binders: Fluorination Enhances Protein Rescue by Exon Inclusion

open access: yesChemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
An adaptable approach, many light‐switchable RNA binders. We report a versatile strategy for rapidly synthesizing photoswitchable RNA binders. The ligands can target SMN2 pre‐mRNA, restoring the levels of the corresponding protein by exon‐inclusion rescue.
