A Novel Synthesis Strategy for Poly(Arylene‐Vinylene) Derivatives by Elemental Sulfur‐Mediated Polyolefination

Macromolecular Rapid Communications, Volume 46, Issue 23, December 5, 2025.
A new synthetic access to poly(arylene‐1,2‐diaryl vinylene) derivatives, a class of conjugated polymers with aggregation‐induced emission properties, via an elemental sulfur‐mediated polyolefination of bifunctional N‐tosyl hydrazones is presented. The described procedure is more convenient and at least similarly effective to established procedures, as ...

Triaza-based amphiphilic chelators : synthetic route, in vitro characterization and in vivo studies of their Ga(III) and Al(III) chelates [PDF]

, 2010
Radiogalium chelates are important for diagnostic imaging in nuclear medicine (PET and ƴ-scintigraphy). Micelles are adequate colloidal vehicles for the delivery of therapeutic and diagnostic agents to organs and tissues.

Aldehyde Hydrosilylation with Ethylzinc Complexes of Bulky β‐Thioketiminate Ligands

Zeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 17, November 25, 2025.
A sterically demanding β‐thioketiminate ligand supports a monomeric ethylzinc complex that catalyses aldehyde hydrosilylation with phenylsilane (PhSiH3). In the presence of methanol (MeOH), high selectivity for the dialkoxysilane product is achieved.

A Robust Heterometallic Pt2Pd2L8 Double Cage Catenane

Angewandte Chemie, Volume 137, Issue 47, November 17, 2025.
The first heterometallic Pt(II)–Pd(II) quadruply interlocked cage catenane (Pt2Pd2L8) has been assembled via a combination of metal‐mediated self‐assembly and dynamic covalent chemistry. The integration of inert Pt(II) and labile Pd(II) ions within the architecture enables facile catenation while strongly enhancing stability of the assembly.
