Three multifluorinated polymer acceptors were designed as the third component for ternary PM6:PY-IT blends. The PM6:PY-IT:PY4F-C20 device exhibited favorable phase separation (∼20 nm) and crystallinity, achieving a device efficiency of 18.0%.
The selection of electronically-different thiolate-based photosensitizers is employed to achieve a precise and specific C–F bond defluorination of a broad range of trifluoromethylarenes, enabling the synthesis of 88 α,α-difluoromethyl compounds.
A mechanochemically induced, nickel-catalyzed one-pot multicomponent protocol for a direct arylative detrifluoromethylation of ArCF3 is described. This reaction represents the first example of C–C coupling with CF3 as a leaving group.
Enantioselective aryldifluoromethyl-alkynylation of alkenes through C(sp3)–F bond activation of ArCF3via photoredox/copper catalysis has been reported for the first time. Various products were synthesized with high yields and enantioselectivities.
To describe the catalytic activity of hydrodefluorination by nickel complexes using molecular volcano plots, multiple reference states must be considered.
