Abstract In situ removable (ISR) solid additive can employ cold sublimation process to optimize active layer morphology for organic solar cells (OSCs), thus remaining unique potential. Herein, a feasible guideline is proposed discover new ISR 1‐bromo‐4‐chlorobenzene (CBB), whose removing time ( T R ) between those of reported additives 1,4‐dichlorobenzene (DCB) and 1‐chloro‐4‐iodobenzene (CIB). The CBB with moderate beneficial affording the optimal achieving highest power conversion efficiency (PCE) 18.58% D18:L8‐BO binary layer, as supported by most efficient exciton splitting, fastest transfer, balanced carrier transports. Due ability, DCB, CBB, CIB are further aggregation PDINN cathode interlayer. Particularly, CBB‐ CIB‐treated interlayers afforded based OSCs excellent PCEs 19.38% 19.26%, along remarkable fill factors 80.98% 81.37%, respectively. suppress non‐radiative recombination devices, resulting in higher open‐circuit voltage. This work not only provides an effective approach flourish but also expands application OSCs.

Sulfur(VI) fluoride exchange (SuFEx) is a second-generation click chemistry reaction that relies on the unique reactivities of SVI–F bonds. The development efficient methods for incorporating S(VI)–F motif into molecules great significance. Sulfamoyl fluorides (R1R2NSO2F), serving as versatile SuFExable hubs, are typically synthesized by using "+SO2F" reagents to establish N-SO2F In this study, we report N-fluorosulfamoyl pyridium salts (NFSAPs) radical fluorosulfonamidation readily accessible and bench-stable. By employing NFSAPs essential fluorosulfamoyl (•NSO2F) precursors, direct installation NSO2F group onto (hetero)arenes alkenes achieved through distinct C–N bond formation reactions. This platform facilitates collective synthesis highly functionalized N-aryl, N-alkyl, N-alkenyl sulfamoyl (R1R2NSO2F) under mild photocatalytic conditions has been applied in late-stage functionalization pharmaceuticals peptides.

Pyridinium-Based Fluorosulfonamide Reagents Enabled Photoredox-Catalyzed Radical Fluorosulfonamidation

Organic Letters, Journal Year: 2024, Volume and Issue: 26(31), P. 6714 - 6719

Published: July 26, 2024

Sulfamoyl fluorides, as a crucial building block of SuFEx, have garnered extensive research interest due to their unique properties. However, the direct radical fluorosulfonamidation process for synthesis sulfamoyl fluorides has been overlooked. We herein disclosed practical procedure constructing redox-active fluorosulfonamide reagent named fluorosulfonyl-N-pyridinium tetrafluoroborate (PNSF) from SO2F2. These reagents can facilitate range reactions, including N-(fluorosulfonyl) sulfonamidation (hetero)arenes, sequential stereoselective fluorosulfonamidation, and 1,2-difunctionalization alkenes.
