•Flexible light-emitting electrochemical cells were fabricated via solution process.•High efficiency was achieved for the blue-green and white luminous devices.•The devices show excellent stability during severe bending test.
In this paper, we demonstrated a simple solution fabrication route to realize flexible single layer light-emitting electrochemical cells (LEC) by employing cationic iridium complexes. The flexible LEC show the efficiency as high as 10.71 cd/A at 5 V and 9.8 cd/A at 7 V for blue-green and white electroluminescence, respectively. Bending test was also performed for the as-fabricated flexible LEC, and they exhibited an excellent light-emitting stability during the multiple mechanical bending at a 10 mm curvature radius.
