Effective electron‐blocking layers (EBLs) for multilayer polymer light‐emitting diodes (PLEDs) have been made by placing a crosslinked network of siloxane and hole‐transporting polymers onto PLED anodes. These EBLs resulted in dramatic performance enhancement of conventional, lectron‐dominated PLED devices: the maximum current efficiency increased tenfold to over 17 cd/A, clearly a result of the effectiveness of the EBL.
