Polymer light‐emitting diodes with doped hole‐transport layers [PDF]

physica status solidi (a), 2011
AbstractWe demonstrate a solution processed bi‐layer PLED based on poly(p‐phenylene vinylene) derivatives using orthogonal solvents. To lower the voltage drop the hole transport layer (HTL) based on poly[2,5‐bis(2′‐ethylhexyloxy)‐co‐2,5‐bis(butoxy)‐1,4‐phenylenevinylene] (BEH/BB‐PPV (1:3)) is doped with tetracyano‐tetrafluoro‐quinodimethane (F4TCNQ ...

1,3-Diphenylethenylcarbazolyl-Based Monomer for Cross-Linked Hole Transporting Layers [PDF]

Molecules, 2015
A new cross-linkable monomer containing 1,3-diphenylethenylcarbazolyl-based hole-transporting moieties and four reactive epoxy groups, was prepared by a multistep synthesis route from 1,3-bis(2,2-diphenylethenyl)-9H-carbazol-2-ol and its application for the in situ formation of cross-linked hole transporting layers was investigated.
