Beyond red/far‐red sensing: phytochrome perception of the marine light field by microalgae

New Phytologist, Volume 250, Issue 5, Page 2837-2844, June 2026.
Summary Phytochromes (PHYs) are a major group of photoreceptors, described as red and far‐red light sensors in land plants. Recent genomic and metagenomic explorations have revealed the presence of PHYs also in various eukaryotic microalgae originating from distinct endosymbiotic events.

Hydantoin-Based Molecular Photoswitches

The Journal of Organic Chemistry, 2015
A new family of molecular photoswitches based on arylidenehydantoins is described together with their synthesis and photochemical and photophysical studies. A series of hydantoin derivatives have been prepared as single isomers using simple and versatile chemistry in good yields.

Ethynylene‐Linked 1,2‐Dihydro‐1,2‐Azaborinines With High Energy Densities for Efficient Molecular Solar Thermal Energy Storage

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
Molecular solar thermal energy storage (MOST) systems offer an approach to harnessing solar energy by converting, storing, and releasing it within chemical bonds. This study introduces ethynylene‐linked 1,2‐dihydro‐1,2‐azaborinines as highly promising candidates for MOST systems, exhibiting exceptional energy densities and extended storage times.

Structural Mechanism of an Efficacy Photoswitch Targeting the β2‐adrenergic Receptor

Angewandte Chemie International Edition, Volume 65, Issue 18, 27 April 2026.
Time‐resolved structures from x‐ray free‐electron laser measurements combined with cellular assays demonstrate how the photoswitchable β‐blocker photoazolol‐1 acts as an efficacy switch of β2‐adrenergic receptor function. Light‐induced ligand repositioning shifts activity from inverse agonism toward neutral antagonism by altering local helical ...
