Substrate‐Affinitive P‐Type Azapolycyclic Photosensitizer for Chemoselective Nitrilization Under Mild Conditions

Advanced Science, EarlyView.
We developed a series of quinoxalinoquinoxaline (QQ) photosensitizers featuring high and tunable excited‐state reduction potentials (E(PC•+/PC*) = –1.76 to –2.05 V vs. SCE). Their hydrogen‐bonding interaction with carbonyl substrates enables selective single‐electron transfer events for selective nitrilization of 1° amides, offering a tunable ...

Electrochemically Induced Oxide‐to‐Hydroxide Transformation Enables Fast Proton Transport for Enhanced Hydrogen Evolution

Advanced Science, EarlyView.
An electrochemically induced transformation of polar MgO(111) into Mg(OH)2(001) creates a proton‐conductive hydroxide layer during hydrogen evolution. Operando synchrotron XRD and DFT reveal a low‐barrier Grotthuss proton‐hopping mechanism, establishing a feasible strategy for designing oxide‐hydroxide electrocatalysts with enhanced proton transport ...

Synthesis and electrochemical characterization of bimetallic ruthenium complexes with the bridging h2(s,s)-1,3-butadiyne-1,4-diyl ligand

Journal of the Brazilian Chemical Society, 2000
The bis(ruthenium)alkyne complex [cis-{RuCl (bpy)2(mu-CºC-)}]2 (1) was obtained by treatment of 1 equiv of either 1,4-bis(trimethylsilyl)-1,3-butadiyne or bis(trimetylsilyl)acetylene with 2 equiv of cis-[RuCl2(bpy)2].2H2O, NaF and NaBF4 salts in methanol/

Rational Design of Broad‐Spectrum Anti‐Enteroviral Molecular Glues Targeting Enteroviral RNAi Suppressors

Advanced Science, EarlyView.
By leveraging this homodimerization mechanism, molecular glues were rationally designed to induce dysfunctional 3A dimerization, thereby restoring antiviral RNAi. The optimal molecular glue, VTP‐32, demonstrated potent and pan‐enterovirus (groups A, B, D) antiviral effects.

Breaking the Bottleneck in Limit of Detection of Surface Refractive Index Sensing by Harnessing Meta‐Waveguide Microring Resonators

Advanced Science, EarlyView.
Mode splitting in meta‐waveguide microring resonators (MWMRs) effectively suppresses baseline drift and measurement noise while maintaining high refractive‐index sensitivity. This reflection‐induced mode splitting strategy enables quantitative detection of ultra‐weak surface perturbations and establishes MWMRs as a robust, drift‐immune platform for ...
