Planar Chiral Carbazole‐Naphthalene Bisimide Hetero‐Cyclophane for Circularly Polarized Delayed Fluorescence

Angewandte Chemie, Volume 138, Issue 35, 24 August 2026.
Tightly stacked carbazole and 1,2:5,6–naphthalene bisimide units afforded a planar chiral hetero‐cyclophane. The architecturally refined system, with strong charge‐transfer interaction and enhanced structural rigidity, exhibits orange‐red delayed CPL emission in both solution and solid states.

Number and Position of Methoxy Substituents Govern Photophysics and Visible‐Light Photocatalysis in Earth‐Abundant Cu(I) Complexes

ChemSusChem, Volume 19, Issue 16, 27 August 2026.
The number and position of methoxy substituents provide a versatile molecular toolbox for tuning the photophysics and visible‐light photocatalytic performance of heteroleptic Cu(I) photosensitizers. Earth‐abundant Cu(I) photosensitizers are promising systems for visible‐light‐driven photocatalysis, but further design guidelines are required to relate ...
