Thermally Bistable Stiff Stilbene Photoswitches and Polymer Applications

The Chemical Record, EarlyView.
Thermally stable photoswitches offer new opportunities for controlling polymer structures and functions under nonequilibrium conditions. This Personal Account highlights stiff stilbene (SS) and sterically hindered stiff stilbene (HSS) photoswitches, which combine large structural changes with exceptional thermal bistability.

Stimuli‐Responsive Poly(Disulfide)s: A Versatile Platform for Intelligent Drug Delivery Systems

MedComm – Biomaterials and Applications, Volume 5, Issue 2, June 2026.
Ring‐opening polymerization based on dynamic disulfide bond exchange is an important method for synthesizing poly(disulfide)s. These polymers possess stimulus‐responsive mechanisms and show broad prospects in intelligent drug delivery. This review systematically discusses the ring‐opening polymerization strategy and research progress of drug delivery ...

Imparting functional variety to cellulose ethers via olefin cross-metathesis

, 2015
Olefin cross-metathesis is a valuable new approach for imparting functional variety to cellulose ethers. Starting from commercially available ethyl cellulose, terminally unsaturated alkyl groups were appended as metathesis handles by reaction with allyl ...

Inter‐/Intramolecular π‐Stacking in a Benzannulated NCN‐Coordinated Pd(II) Monomer and Dimer Pair: Synthesis, Structure, and Photophysics

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 7, 6 May 2026.
A cyclometalallated palladium complex and its acetate‐bridged dinuclear analogue, both supported by 1,3‐bis(2‐quinolinyl)benzene ligands, are described. The mononuclear (but not the dinuclear) complex is weakly phosphorescent in the deep red region of the spectrum in solution at room temperature, and both compounds phosphoresce in frozen media at 77 K ...

Design, Synthesis, and Structural Analysis of Binaphthyl‐Based Chiral Benzindenes

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
This work explores the synthetic endeavors in constructing the first‐of‐a‐kind axially chiral benz[f]indenes as potential chiral ligands. The overall synthetic pathway spans across 9 steps with 15.9% overall yield. Challenges in constructing modified analogs as well as metal complexes are discussed. Chiral benzindenes are an unexplored structural motif

Elucidation of the Conformational Rate Processes of the Macrocyclic Lactone (–)‐Nonenolide Through Variable Temperature NMR, Quantum Mechanics, and Molecular Dynamics

European Journal of Organic Chemistry, Volume 29, Issue 17, 5 May 2026.
The conformational rate processes that influence the NMR spectra of the ten‐membered lactone (–)‐nonenolide are elucidated using VT‐NMR, QM calculations and MD simulations. Reorientation of the alkene moiety with respect to the ring is identified as the slow exchange process.

Light‐Driven Competitive Selection in a Protein‐Catalyzed Dissipative Peptide Replication

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
A structurally flexible protein catalyzes replication within a dissipative reaction network driven by UVA‐induced disulfide rearrangements. The protein accelerates templated autocatalytic cycles with replication emerging as the dominant pathway.

Laser Engineering of HfN‐Based Nanoparticles for Safe NIR‐I Photothermal and X‐ray Enhancing Cancer Therapies

Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
In this study, we produced HfN‐based nanoparticles via femtosecond laser ablation in acetone. The nanoparticles exhibit a red‐shifted plasmonic resonance in the NIR‐I window, colloidal stability after coating with polyethyleneglycol, and excellent biocompatibility. The photothermal and X‐ray sensitization therapeutic effects were demonstrated for tumor

Chemical Upcycling of Nitrile Butadiene Rubbers to Polyamines and Polyols by Chemoselective Catalytic Hydrogenation

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
We demonstrate here the transformation of NBR (Nitrile butadiene rubber) including post‐consumer waste sourced from nitrile gloves and o‐rings into polyamines and polyols via ruthenium catalyzed hydrogenation. ABSTRACT We report here two new approaches for the chemical recycling/upcycling of nitrile butadiene rubber (NBR) to make either polyamines or ...
