Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

Advanced Materials Technologies, Volume 11, Issue 15, 7 August 2026.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

Biocatalytic Application of Goodfellowiella coeruleoviolacea Imine Reductase: Enantioselective Synthesis of Cyclic Secondary Amines in Deep Eutectic Solvent‐Based Media

Advanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
A Goodfellowiella coeruleoviolacea Imine Reductase is here reported as a novel enzyme for biocatalytic application in chiral amine synthesis. Deep eutectic solvents have been used to increase substrate loadings, up to 150 mM, and boost enzymatic activity. Reaction scope and scale‐up procedure showcased the protocol applicability.

Synergistic Mechanism Between Ir–Phosphinito Catalyst and HFIP Enables Asymmetric Hydrogenation of Ketones Under Acidic Conditions

Advanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
A cooperative mechanism between a phosphinito Ir complex and HFIP provides a low‐energy pathway for hydrogen activation. This allowed the development of a highly efficient catalytic system for the hydrogenation of ketones that operates under acidic conditions, enabling the reduction of substrates containing phenols and carboxylic acids with no added ...

Synthesis and Characterization of Tritium‐Labeled Neuropeptide Y Y5 Receptor Ligands Derived From CGP71683A

Archiv der Pharmazie, Volume 359, Issue 8, August 2026.
From a synthesized series of 2,4‐diaminoquinazoline‐type Y5R ligands, three were prepared as tritium‐labeled compounds and characterized by saturation equilibrium binding at HEC‐1B‐hY5R cells. [3H]32 was further applied in a competition binding assay. High non‐specific binding of the radioligands prompted investigation of material‐dependent adsorption.
