Catalytic C–F Bond Activation at Room Temperature: Enolate Cross‐Couplings Enabled by [Pd(1‐MeNAP)TFA]2 and LiHMDS

open access: yesAngewandte Chemie International Edition, EarlyView.
Catalysts generated from the trifluoroacetate‐bridged methylnaphthyl‐palladium dimer [Pd(1‐MeNAP)TFA]2 and biarylphosphine ligands in combination with the base LiHMDS promote α‐arylation reactions of various enolates with non‐activated aryl fluorides at room temperature.

Design, Synthesis, and Photovoltaic Characterization of Thiophene‐Linked Phenazine Copolymers for Solar Energy Conversion

open access: yesJournal of Applied Polymer Science, EarlyView.
Side‐chain engineering represents an effective molecular strategy for tuning the optoelectronic properties and solid‐state organization of conjugated polymers for organic photovoltaic applications. In this study, two donor–acceptor copolymers, PBDT‐DT‐BODFPz and PBDT‐DT‐EHDFPz, were synthesized via Stille polymerization using benzodithiophene (BDT) and

The roles of side chains in Y6‐series non‐fullerene acceptors for high‐performance organic solar cells

open access: yesBulletin of the Korean Chemical Society, EarlyView.
The development of organic solar cells (OSCs) has been driven by structural modifications of Y6‐series non‐fullerene acceptors. In particular, side‐chain engineering regulates solubility, molecular packing, and energy levels, enabling efficiencies to increase from 15.7% to over 20%.

Solvent vapor annealing effect on organic solar cells based on a nonfullerene acceptor

open access: yesBulletin of the Korean Chemical Society, EarlyView.
A new non‐fused nonfullerene acceptor, FBTT‐BORH, featuring a monofluorinated benzothiadiazole core and rhodanine end groups, was synthesized for organic solar cells. Solvent vapor annealing treatment significantly improved the power conversion efficiency from 5.12% to 6.73% by promoting J‐type aggregation, increasing electron mobility by 24‐fold, and ...
