Chemical Syntheses of 3′ and 5′ Phosphorylated Oligonucleotides: An Overview

European Journal of Organic Chemistry, Volume 29, Issue 21, 4 June 2026.
This review provides an overview of the various chemical methods employed in the synthesis of oligonucleotides bearing a phosphate group at their 3′ or 5′ end. Notably, it presents modified phosphoramidites and supports developed for this purpose. Oligonucleotides (ON) with a phosphate monoester group at their 3′ or 5′ end have applications in many ...

Lighting the Path to Cyclic Phosphonamides via Halogen‐Bond Electron Donor–Acceptor Activation

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
Cyclic phosphinamides are valuable scaffolds for optoelectronic applications, yet remain difficult to access with existing methods. Here, we highlight a mild and straightforward visible light‐driven strategy that enables the formation of cyclic phosphinamides and thiophosphinamides.

From Strain to Pressure: Atomically Resolved Mechanisms of Stress Dissipation in Emissive, Elastically Deformable Molecular Crystals Under Ambient and High Pressure

Advanced Optical Materials, Volume 14, Issue 21, 5 June 2026.
Molecular crystals must withstand both isotropic and anisotropic stress to function in flexible optoelectronics and high‐pressure devices. In situ high‐pressure single‐crystal X‐ray diffraction coupled with DFT‐D computations reveal how an emissive molecular crystal with interdigitated packing bends elastically at ambient‐pressure and remains ...

Ion‐Pairing and Counterion Effects in Contemporary Photochemistry

Angewandte Chemie Novit, Volume 2, Issue 2, June 2026.
Ion‐pairing and counterion effects have emerged as fundamental yet underexplored determinants of photochemical behavior. Far from inert, counterions, and Coulombic interactions modulate excited‐state dynamics, quenching efficiencies, emission, and catalytic pathways.
