• new cathode interlayer (CIL) materials based on bay N-annulated perylene diimides. Starting from the previously reported N-annulated perylene diimide (PDIN-H), the N-position was functionalized with a benzyl and pentafluorobenzyl group to make PDIN-B and PDIN-FB, respectively. Similarly, starting from

• they can be easily structurally characterized, have highly reproducible syntheses, and can exhibit high solubilities in common organic solvents for effective solution processing and thin film formation. Towards obtaining high-performance CIL materials, perylene diimides (PDIs) stand out as excellent

• pressure that can lead to precipitation during coating and due to being a highly flammable and toxic solvent [20][33][34]. Figure S33 in Supporting Information File 1 compares the J–V characteristics of all N-annulated perylene diimides-based CILs cast from ethyl acetate and PFN-Br cast from methanol

Naphthalene diimides (NDIs) as the smallest possible rylene dyes are such an important class of organic dyes. In contrast to their bigger homologs perylene diimides which were rarely used for photoredox catalysis
