Charge Injection and Transport in an Isoindigo‐Based Polymer Transistor

open access: yesAdvanced Electronic Materials, EarlyView.
This study presents the charge injection and transport properties of field‐effect transistors based on an isoindigo‐bithiophene donor‐acceptor polymer semiconductor contacted with thiolated self‐assembled monolayer (SAM)‐functionalized electrodes. Temperature‐dependent contact characteristics are measured and simulated.

Discerning Blend Microstructure and Charge Recombination for Stable Biorenewable‐Based Organic Photovoltaics

open access: yesAdvanced Energy Materials, EarlyView.
A combination of morphological, electrical, and spectroscopy techniques is used to evaluate the degradation mechanisms of non‐fullerene (NFA)‐based organic photovoltaics (OPVs). Blends based on Y12 are more stable than Y6, aspeciallyOPVs from FO6‐T:Y12 demonstrated superior stability with an extrapolated T80 of over 2000 hours under maximum power point

Stereoselective Construction of Tertiary Homoallyl Alcohols and Ethers by Nucleophilic Substitution at Quaternary Carbon Stereocenters

open access: yesAngewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
A highly efficient stereoinvertive nucleophilic substitution at the quaternary carbon stereocenter of cyclopropyl carbinol derivatives using water, alcohols and phenols as nucleophiles is reported. A variety of highly sterically hindered tertiary alkyl ethers and alcohols with adjacent tertiary carbon stereocenters are obtained in good yields with ...

The Effect of Pore Functionality in Multicomponent Covalent Organic Frameworks on Stable Long‐Term Photocatalytic H2 Production

open access: yesAdvanced Energy Materials, EarlyView.
Five COFs are synthesized through a multicomponent reaction, preserving a similar backbone while introducing varying pore functionalities. All COFs demonstrate excellent chemical stability and sustained H2 production under sunlight for 7‐15 days. The imidazole‐functionalized COF exhibits the highest H2 production, which can be attributed to its high ...
