We designed and synthesized poly 4,4'-(2-(4-((4-hexylphenyl)(phenyl)amino)phenyl)-9H-fluorene-9,9-diyl)bis(N,N-bis(4-butylphenyl)aniline)], (PFTPA_biTPA) as hole transport layer of solution-processed organic light-emitting diodes (OLEDs). we photo-crosslinkable hole transporting layer (HTL) consisting of a blend of PFTPA_biTPA was applied to red and green organic light-emitting diodes (OLEDs) by solution processing. The solvent resistance of the photo-crosslinked PFTPA_biTPA :FPA film was enhanced compared to that of the non-crosslinked neat PFTPA_biTPA. And solution-processed red and green OLEDs with the PFTPA_biTPA: FPA1.5 wt%) photo-crosslinked HTL exhibited good device performances. |
