Imide-fused diazatetracenes : synthesis, characterization, and application in perovskite solar cells
A series of imide-fused diazatetracenes were synthesized via Buchwald-Hartwig C-N coupling with a highly active palladium source. The introduction of an imide segment effectively lowers the LUMO levels compared with that of unsubstituted diazatetracene. By adjusting the alkyl chains of the diazatetr...

| description | A series of imide-fused diazatetracenes were synthesized via Buchwald-Hartwig C-N coupling with a highly active palladium source. The introduction of an imide segment effectively lowers the LUMO levels compared with that of unsubstituted diazatetracene. By adjusting the alkyl chains of the diazatetracenes, different solid-state packings were achieved, resulting in distinct photoluminescent behaviors. Their electron-transporting properties were demonstrated in the proof-of-concept Perovskite solar cells as electron transporting layers. |
