Chemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.Visible‐light irradiation of nitro‐perylenediimide in the presence of triphenylphosphine reveals an unexpected pathway competing with the classical Cadogan cyclization. Mechanistic investigations uncover the rapid and selective formation of bay‐functionalized 1‐iminophosphorane‐12‐hydroxy perylenediimide derivatives.

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.Two spirobisanthracene‐tetraphenylethene (SBA‐TPE) hybrid compounds are synthesized and their photophysical properties in the solid state reported. Circularly polarized luminescence in aggregates, films and dispersions is evaluated. Circularly polarized luminescence imaging is evaluated over crystals revealing discrimination of different types of ...

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...

ChemBioChem, Volume 27, Issue 11, 15 June 2026.BODIPY‐decorated monofunctional Pt(II) complexes were computationally designed as dual chemo‐photodynamic agents. π‐conjugation engineering shifts absorption into the therapeutic window (up to 661 nm) while preserving singlet oxygen generation and DNA platination capability.

Nanophotonics, Volume 15, Issue 11, 13 June 2026.Backward optical parametric oscillation is realized in a submicron‐poled thin‐film lithium niobate microring. By engineering the quasi‐phase‐matching condition, both type‐0 and type‐I degenerate oscillation emerge in the same device and are selectively accessed through temperature tuning, providing a versatile on‐chip platform for polarization‐diverse ...

Ground‐ and Excited‐State Mixed Valency in a 4,4′‐Bipyridine‐Bridged Bimetallic Di‐Ruthenium Complex
European Journal of Inorganic Chemistry, Volume 29, Issue 16, 4 June 2026.Photoinduced mixed‐valence interactions across a 4,4′‐bpy bridge were studied. MLCT excited states in the bimetallic complex are longer‐lived than in the monometallic reference, thanks to metal–metal electronic coupling and hole delocalization, but are still shorter than the nanosecond timescale relevant for diffusional reactivity.

Decoding THz‐Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks
Advanced Materials, Volume 38, Issue 32, 8 June 2026.ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...

Advanced Theory and Simulations, Volume 9, Issue 6, June 2026.Using the analytic cross‐section morphing of wurtzite nanowires to arbitrary shapes (König, Bian, Fu, and Smith, Adv. Theo. Simul. 2025, 8 2400951), the cross‐section shape with the maximum number of nanowire‐internal bonds per nanowire atom is derived, representing the most stable intrinsic crystalline form (structural‐thermodynamic optimum).
