Emissive Liquid Crystalline Boron C,N‐Chelates: Synthesis, Self‐assembly, and Photophysical Properties

Chemistry – A European Journal, EarlyView.
Novel emissive liquid crystalline boron C,N‐chelates were prepared by integrating mesogenic units into the boron C,N‐core. Depending on the substituent at the boron, stable SmA or N mesophases were achieved while maintaining intense blue emission with excellent quantum yields (61%–100%).

Chain Versus Ring: Characterization of a Meta‐Phenylene Ladder Polymer and Its Octameric Macrocycle

Chemistry – A European Journal, EarlyView.
The synthesis and comprehensive spectral and photophysical analysis of a methyl‐substituted ladder meta‐phenylene macrocycle (MeLMMP) and its polymer analogue (MeLPMP) show that, despite differing topologies (macrocycle vs. polymer), both display nearly identical electronic and photophysical properties due to cross‐conjugation.

A Facile Protocol for C(sp2)–C(sp3) Bond Formation Reactions Toward Functionalized E3 Ligase Ligands

ChemMedChem, EarlyView.
A robust C(sp2)–C(sp3) decarboxylative coupling strategy enables access to new CRBN ligands and degraders with improved physicochemical properties. This synthetic approach is expanding the chemical space beyond C(sp2)–N linkages, fine‐tuning proteolysis‐targeting chimera activities and unlocking previously inaccessible degrader chemotypes.

Recent Developments in the Field of Air‐Stable Nickel(0) Precatalysts for Cross‐Coupling Reactions

European Journal of Inorganic Chemistry, EarlyView.
The development of bench‐stable Ni(0) sources aims to replace air‐sensitive [Ni(COD)2] (cod = cycloocta‐1,5‐diene) with easy‐to‐handle alternatives. Through a targeted ligand design, using electron‐deficient dienes, carbenes, and fluorophosphines, researchers have achieved air‐ and moisture‐tolerant complexes that show high catalytic activity in cross ...

T‐Shaped 8‐Aryl(ethynyl)‐Substituted Psoralens With Tunable Charge‐Transfer Absorption

European Journal of Organic Chemistry, EarlyView.
Starting from 8‐methoxypsoralen, new 8‐arylated and 8‐alkynylated psoralen derivatives are accessible by cross‐coupling. These T‐shaped π‐expanded chromophores are luminescent and photophysics reveal a highly polar excited state with tunable charge‐transfer character.
