A carbazole functionalized AIE molecule was constructed and applied as a precursor to prepare the luminescent network films for organic light-emitting devices (OLEDs) by electrochemical polymerization. The resultant cross-linked electrochemically polymerized films have smooth surface and exhibit high thermal stability. OLEDs with these films as light emitting layer have a maximum luminance of 489 cd m−2, a maximum luminance efficiency of 0.38 cd A−1, and a turn-on voltage of 3.4 V. These results indicate that electrochemical synthesis can be a new facile route for constructing the cross-linked polymer luminescent films with AIE molecules, which show potential applications in OLEDs.
