Kinetics of anionic polymerization of β‐myrcene in hydrocarbon solvents

Polymer International, EarlyView.
The process of anionic polymerization of β‐myrcene in hydrocarbon solvents was examined by kinetic studies and quantum chemical calculations. Abstract The kinetics of anionic polymerization of β‐myrcene initiated by sec‐butyllithium were examined in saturated and unsaturated hydrocarbon solvents, i.e. cyclohexane, cyclohexene, 4‐vinylcyclohexene and dl‐

Living Coordination (Co)Polymerization of Norbornene Derivatives by Using Nickel Catalysts Derived From Bis(1,5‐Cyclooctadiene)nickel(0) and 2,6‐Dihydroxybenzoic Acid

Journal of Polymer Science, EarlyView.
The living coordination polymerization of norbornene is achieved using a nickel catalyst derived from Ni(cod)2 and 2,6‐dihydroxybenzoic acid with trityl borate as cocatalyst to produce poly(norbornene) with controllable molecular weights and narrow polydispersity.

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.

Ba[C(CN)3]2 and Pb[C(CN)3]2: Two Remarkably Different Heavy Main‐Group Metal Bistricyanomethanides

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Metathesis reactions of either barium dichloride, BaCl2, or lead dichloride, PbCl2, respectively, with Ag[C(CN)3] in water yielded single crystals of anhydrous Ba[C(CN)3]2 and Pb[C(CN)3]2. Ba[C(CN)3]2 crystallizes in the monoclinic space group P21/n (no. 14) with the lattice parameters a = 437.98(3) pm, b = 1685.36(11) pm, c = 1398.87(9) pm, β = 96.541(

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 ...

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 ...
