Hybrid Macrocyclic Peptides — Synthetic Strategies to Diversify and Cyclize Peptide Libraries in Phage Display Selections

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the

Orchestrating Anion–π+ Interactions to Accelerate Metal‐Free Room‐Temperature Phosphorescence

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
Tuning anion–π+ interactions in pyridinium iodide contact ion pairs enables ultrafast metal‐free room‐temperature phosphorescence (540–605 nm) with radiative rates up to 5.2×105 s−1. Strong iodide→π+ charge‐transfer coupling, enhanced spin–orbit interactions, and dynamic ion‐pair organization accelerate intersystem crossing and emission, establishing ...

Structural and Spectroscopic Evidence of Hydrogen Bonded Anionic Wires in Protic Ionic Liquids

ChemPhysChem, Volume 27, Issue 19, 14 October 2026.
Anionic wires of deprotonated carboxylic acids challenge the general wisdom that like charges repel. The hydrogen bond motif observed in the X‐ray structure is even preserved in the liquid state of the material as shown by δ1H NMR spectroscopy. The experimental and theoretical findings provide deep insight into the nature of hydrogen bonding.

Encapsulation of Porphyrins in Polymer Microgels and Microbeads for Heterogeneous Photooxidation

ChemSusChem, Volume 19, Issue 19, 14 October 2026.
Amino‐ or ammonium‐functionalized tetraphenylporphyrins were synthesized and encapsulated within polymers to form microgels and microbeads that act as heterogeneous photocatalysts. Photooxidation in aqueous media quantitatively converts sulfides and aldehydes into sulfoxides and carboxylic acids via the singlet‐oxygen pathway, demonstrating an ...
