Rational Molecular Engineering of Amidonaphthoquinone Cathodes: Precise Hydrogen Bond and Size Control for High‐Performance Lithium Organic Batteries

open access: yesAdvanced Science, EarlyView.
This work provides a novel molecular design strategy to develop three naphthoquinone‐derived cathodes (NQ1, NQ2, and NQ3) by linking one, two, and three amido‐naphthoquinone redox centers onto a benzene ring in a convenient way. Structure evolution to increased hydrogenbonds and molecular size enables high performance LOBs by joint solubility suppress ...

Ligand‐Engineered Metal–Organic Frameworks of 3D Infinite Trinuclear Zinc Units for Photocatalytic Monooxygenation of Sulfenamides

open access: yesAdvanced Science, EarlyView.
The rarely investigated metal–organic frameworks (MOFs) of 3D infinite trinuclear zinc units are designed and synthesized. Through controllable programming of ligands, their Lewis acidity and photoactivity are fine‐tuned to enable these MOFs as promising catalysts for the cycloaddition of CO2 and photocatalytic monooxygenation of sulfenamides and ...

Confinement‐Induced Metastable Supramolecular Assembly: Dynamic Built‐in Electric Field Driving Deep Mineralization of Organic Pollutants

open access: yesAdvanced Science, EarlyView.
Utilizing the 2D confined space of layered double hydroxide (LDH), living supramolecular assembly (LSA) are successfully prepared with smaller intermolecular distances than in crystals. The IEF enhancement value can reach 11.8 times, which induces a charge separation efficiency of 71.52%.

Bandgap‐Dependent Doping of Semiconducting Carbon Nanotube Networks by Proton‐Coupled Electron Transfer for Stable Thermoelectrics

open access: yesAdvanced Electronic Materials, EarlyView.
Proton‐coupled electron transfer doping with benzoquinone is applied to p‐dope dense films of semiconducting single‐walled carbon nanotubes. The doping efficiency depends on the pH of the doping solution and the bandgap of the nanotubes. The highest conductivities and power factors are achieved for small‐bandgap nanotubes, remaining stable for over 120

Solution‐Processed Sterically Hindered Donor–Acceptor Small Molecules as Molecular Floating‐Gates for High‐Efficiency Ambipolar Charge Trapping Memory

open access: yesAdvanced Electronic Materials, EarlyView.
High‐efficiency ambipolar multilevel nonvolatile organic transistor memory using solution‐processing a sterically hindered small molecule spiro[fluorene‐9,7′‐dibenzo[c,h]acridine]‐5′‐one with donor–acceptor structures as charge trapping layer is demonstrated.

Designer Electrocatalysts for the Oxygen Reduction Reaction with Controlled Platinum Nanoparticle Locality

open access: yesAdvanced Energy Materials, EarlyView.
Pt/C catalysts differing only in the locality of the Pt nanoparticles, whether inside or outside of the pores of the same carbon support, are needed to study the effect of said locality. Depending on the carbon support used, nanoparticles inside the pores can show hindered accessibility and ORR performance.

Fe‐N‐C in Proton Exchange Membrane Fuel Cells: Impact of Ionomer Loading on Degradation and Stability

open access: yesAdvanced Energy Materials, EarlyView.
The impact of the ionomer to catalyst ratio for atomic Fe in N‐doped C (Fe‐N‐C) degradation in proton exchange membrane fuel cells is elucidated by advanced electrochemical techniques. Kinetic degradation dominants, with the reduction in turnover frequency of FeNx active sites initially suppressed with increasing ionomer loading.
