Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.
Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

A Portal‐Preorganized Cucurbit[7]uril‐Ruthenium Conjugate Enables Motif‐Selective Protein Sensing

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 44, 26 October 2026.
Reprogramming cucurbit[7]uril (CB7) recognition through portal engineering transforms an optically silent host into a motif‐selective photoluminescent receptor. The portal‐preorganized CB7‐Rubpy conjugate directly reports changes in aromatic motif accessibility, enabling optical sensing of protein misfolding and refolding.

Thermally Activated Delayed Fluorescence: An Extended Study of Peripherally Substituted DMAC‐TRZ Analogues

open access: yesChemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
A comprehensive experimental and theoretical study is presented of a family of TADF dyes. Comparing the behavior of structurally related dyes, we uncover the subtle and somewhat unexpected role of conformational degrees of freedom associated with peripheral groups that affect the delicate interplay of excited states that governs spin–orbit coupling ...

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

open access: yesChemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
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 ...
