Indenone-fused N-heteroacenes

Abstract

The synthesis and optical, electronic and structural properties of indenone-fused azaacenes, as well as their ambipolar behaviour, are reported.

Sky-Blue Thermally Activated Delayed Fluorescence with Intramolecular Spatial Charge Transfer Based on a Dibenzothiophene Sulfone Emitter

“…This phenomenon gives rise to aggregation-induced emission behavior, which increases the PLQY in the solid state (Figures S15 and S16). ,− The details will be described in the part of photophysical properties.…”

High-performance five-ring-fused organic semiconductors for field-effect transistors

“…42), 446 thiadiazole (494-499, Fig. 42), [447][448][449][450] hybrid benzofuran, benzothiophene and thienopyrrole (501 and 502, Fig. 42), 438 selenophene and thiophene (503 and 504, Fig.…”

Recent progress in pyrazinacenes containing nonbenzenoid rings: synthesis, properties and applications

“…For example, introducing the electron-withdrawing carbonyl group on the protruded carbon atom of diazaindenone can not only enhance the electron accepting ability, 66,71,72 but also restore the whole conjugated character of resultant azaacenes. In 2019, the Gao group 53 synthesized the indanone-fused azaacenes 27ba–bc and 28ba with different end-capped groups via the one-step condensation reactions between aromatic diamines and trione derivative 26b in AcOH under 100 °C (Scheme 4a). In addition, in order to understand the impact of different fused units, 28c fusing with a thienyl unit was also prepared in a similar manner.…”
