Abstract

Two regioisomers of naphthothiadiazole derivatives with aggregation-induced emission enhancement exhibited a strong solid-state fluorescence emission in the range of 666-760 nm. A non-doped EL device emitted brilliant near infrared emission peaked at 754 nm with a high maximum radiance of 22 050 mW Sr-1 m-2, an EQE as high as 1.48%, and relatively low efficiency roll-off.
