Charge-transfer modulated chiroptical azacyclooctatetraene-fused [5]helicenes with AIE features

Integrating eight-membered diazacyclooctatetraene-fused aza[5]helicene scaffolds with tailored charge-transfer yields AIE-active CP-TADF emitters exhibiting broad spectral tunability (555–842 nm) and strong chiroptical activity (| g PL | ≈ 1.5 × 10 −2 ).
