Reduced Symmetry Metal–Organic Cage‐to‐Framework Materials

open access: yesAngewandte Chemie, Volume 138, Issue 26, 22 June 2026.
A series of Ag(I) MOFs was synthesised from organic cages of varying structure and symmetry as linkers. Minor variations in the cage linkers were shown to significantly influence the structures of the resulting MOFs. This work represents the first incorporation of reduced symmetry (including chiral), intrinsically porous building blocks into MOFs, and ...

Electrochemical investigation of radical‐radical recognition in viologen‐based ditopic structures

open access: yesResponsive Materials, EarlyView.
The so‐called “blue box” is one of the most studied macrocycles. Yet, functionalized macrocycles of this type are rarely investigated. This work describes the radical‐radical recognition properties of ditopic structures, including functionalized blue‐box macrocycles.

Toward Sustainable Carbonylation Reactions Enabled by CO Surrogates in Green Solvents

open access: yesChemSusChem, Volume 19, Issue 13, 14 July 2026.
Carbonylation reactions offer a sustainable route to valuable carbonyl compounds. This review highlights methodologies that exploit carbonylative coupling to drastically enhance process sustainability, avoiding the direct use of CO through CO surrogates and promoting syntheses in green solvents potentially derived from renewable and sustainable sources.

“Click” Synthesis of Nonsymmetrical Bis(1,2,3-triazoles)

open access: yesOrganic Letters, 2010
Unsymmetrically 1,1'-disubstituted 4,4'-bis-1H-1,2,3-triazoles 4 have been prepared from 4-ethynyl-1,2,3-triazoles 5 and azides. Following a "double-click" strategy, two complementary approaches were implemented for the preparation of the key 4-ethynyltriazole intermediates 5: (a) the stepwise Swern oxidation/Ohira-Bestman alkynylation of readily ...

An Overview of Pterin Analysis in Biological Samples: From Occurrence and Properties to Sample Pretreatment Combined With Hyphenated Separation Techniques

open access: yesJournal of Separation Science, Volume 49, Issue 7, July 2026.
ABSTRACT Pterins are a structurally diverse group of biologically active compounds within the pteridine family, with key roles in pigmentation, redox metabolism, light sensing, and cellular signaling across a wide range of organisms. Their quantification in biological samples is analytically demanding due to their high polarity, chemical instability ...
