Control of Photoinduced Charge Transfer Through Selective Cyanation of Spirofluorene-Bridged N-Heterotriangulenes (Advanced Optical Materials 27/2024)

Selectively Functionalized Spirofluorene-Bridged N-Heterotriangulene

The cover page visualizes the cyanated spirofluorene-bridged N-heterotriangulenes surrounded by a mesmerizing aurora borealis, whose vibrancy symbolizes the dynamic nature of the photoinduced charge-transfer process occurring in the compounds synthesized by Milan Kivala and co-workers (see article number 2401656). Highlighted are the tripod-like shapes and the strategic placement of the cyano groups, which are crucial for tuning the optoelectronic properties. The Earth with a glimpse of the Sun illustrates the relevance of the authors' findings in the context of future energy-efficient applications to mitigate society's impact on the environment and climate.
