Synthesis and Optical Properties of Diboron Complexes of 1,4‐Anthraquinone Derivatives

Chemistry – A European Journal, EarlyView.
1,4‐Diboron complexes exhibit near‐infrared fluorescence, in contrast to non‐emissive 1,5‐diboron analogues. Fluorescence quantum yields decrease with increasing electron‐donating substituents, attributed to enhanced nonradiative decay via intramolecular PeT.

Photosensitizing Au(I) Catalysis With Coumarins

Chemistry – A European Journal, EarlyView.
A Au(I) complex with a tethered coumarin fragment was synthesized and characterized by UV‐vis and emission spectroscopy. Its ability to facilitate photo‐driven cross‐coupling reactions through single‐electron and energy transfer events was evaluated. ABSTRACT Gold catalysis shows versatility in a wide range of challenging transformations, wherein light‐

Prism[5]MaxQ: A Sulfated Prism[5]Arene and Its Molecular Recognition Properties Toward a Panel of Quaternary Ammonium Guests

Chemistry – A European Journal, EarlyView.
We report the synthesis and characterization of a sulfated prism[5]arene host (Prism[5]MaxQ). Prism[5]MaxQ displays ultrahigh binding affinity (Ka up to 1012 M−1) toward hydrophobic (di)cations in phosphate‐buffered saline (PBS). The work positions Prism[5]MaxQ as a new member of the family of ultrahigh‐affinity hosts poised for use as a sequestrant in

Decoding Heptazine Architectures: From Molecular Association to Structural Insight

Chemistry – A European Journal, EarlyView.
A comprehensive study (NMR and theoretical) of three novel heptazine derivatives that self‐assemble into dimers has been conducted, highlighting their versatility as a platform for multifunctional supramolecular and optoelectronic materials. ABSTRACT Heptazine (Hpz) derivatives display remarkable supramolecular organization governed by noncovalent ...

Modular One‐Pot Access to π‐Expanded Tetrakis(Phenothiazinyl)‐Silanes With Broadly Tunable Redox and Emission Properties

Chemistry – A European Journal, EarlyView.
A library of 21 tetrakis(phenothiazinyl)‐substituted silanes with broadly variable substituent decoration, which are fully reversible multistage redox systems with intense tunable emission from deep blue to yellow–green (441–533 nm), was rapidly synthesized by bromine–lithium exchange/borylation–Suzuki coupling of tetrakis(4‐bromophenyl)silane or by ...
