Mg2+ Ions as Interfacial Charge Bridges for Enhanced Photocatalytic Hydrogen Evolution in Poly(Heptazine Imide)

open access: yesSmall, EarlyView.
Mg2+ confined within poly(heptazine imide) acts as a heterogenized interfacial charge bridge capable to couple synergistically the semiconductor with Pt co‐catalysts, thus enhancing hydrogen evolution. Through water polarization and hydroxide stabilization, a dynamic Mg2+‐OHδ−‐Hδ+‐Pt motif facilitates proton transfer and overcomes interfacial electron ...

Molecularly Regulated Dynamic Interfaces in 3D/2D Perovskites Enabled by Functional Pyridinium Ionic Liquids

open access: yesSmall, EarlyView.
1‐butyl‐4‐methylpyridinium tetrafluoroborate (BMPyBF4) interacts with excess PbI2 during film formation, driving the formation of a low‐dimensional perovskite phase and enabling the self‐organization of a 3D/2D interfacial structure. This molecularly regulated interface suppresses defect‐mediated recombination and facilitates interfacial charge ...

Resonance‐Enhanced Four‐Wave Mixing Imaging for Mapping Defect Regions in Vanadium‐Doped WS2 Monolayers

open access: yesSmall Methods, EarlyView.
Resonant four‐wave mixing (FWM) microscopy reveals a spatial modulation of the third‐order nonlinear optical response in vanadium‐doped WS2 monolayers. This robust nonlinear contrast technique tracks the preferential accumulation of vanadium dopants along the structural bisection lines of the synthesized flakes.

Visible‐Light‐Induced Carbon–Hydrogen Phosphonylation of Conjugated Polymers via Electron Donor–Acceptor Complex Activation

open access: yesAngewandte Chemie, Volume 138, Issue 40, 28 September 2026.
Electron donor–acceptor (EDA) complex activation enabled the efficient transformation of conjugated polymers. Compared with the small‐molecule model compound, the polymers reacted more efficiently, achieving quantitative conversion of PFO. This result demonstrates a new platform for incorporating conjugated polymers into EDA‐mediated photochemical ...

Competing Charge Transport Pathways: A Spirobifluorene‐Based Molecular Loop

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 37, 1 October 2026.
A rigid molecular loop integrating a spirobifluorene (SBF) core with a cycloparaphenylene (CPP) moiety provides two distinct transport channels. Through‐space spiroconjugation and radial π‐conjugation along a CPP backbone coexist within a single molecule.
