Improving the Mechanical Properties of Biodegradable Polyhydroxyalkanoates via PHA–PHA Block‐Copolymer Synthesis

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
Covalent linkage of a highly crystalline PHBV with a ductile P3HB4HB is shown to produce block copolymers with markedly enhanced extensibility and toughness, outperforming equivalent blends. The results demonstrate that polymer architecture, not composition alone, governs mechanical response, offering a route to biodegradable materials that combine ...

RhodaMal Dyes: Novel Red Emissive Fluorophores as Probes for High Contrast Live‐Cell Imaging

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
Incorporation of malononitrile into the traditional rhodol framework furnishes RhodaMal (Rhoda = Rhodamine, Mal = Malononitrile;) dyes, a new class of red emissive push–pull chromophores. Conjugating them to triphenylphosphonium cation enables live cell super‐resolution STED microscopy with a 775 nm depletion laser.

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

Angewandte 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.

Chelation‐Assisted Metal‐Catalyzed Ligation and Cleavage Reactions for Chemical Biology

European Journal of Organic Chemistry, Volume 29, Issue 39, 22 October 2026.
Chelation‐assisted transition metal catalysis has emerged as a promising complement to bioorthogonal click chemistry for studying biological processes. By pre‐organizing catalytic metal centers, designed coordinating substrates enhance reactivity and biocompatibility, enabling site‐selective ligation and decaging reactions in complex biological media ...

Resolution Approaches Toward Enantiopure Planar Chiral 7‐bromo‐4‐hydroxy [2.2]paracyclophane

European Journal of Organic Chemistry, Volume 29, Issue 39, 22 October 2026.
This work describes access to both enantiomers of planar chiral 7‐bromo‐4‐hydroxy [2.2]paracyclophane through direct resolution of the racemate using an L‐isoleucine‐derived chiral auxiliary or through resolution of 4‐hydroxy [2.2]paracyclophane, followed by regioselective bromination.
