Abstract

Newly designed and synthesized hole transport material (HTM) composed of thermal cross-linkable benzocyclobutene (BCB) [(7-(2-((4-vinylbenzyl) oxy)ethoxy) bicyclo[4.2.0]octa-1(6),2,4-triene)) and charge transport indenocarbazole (IC), having low cross-linking temperature of 130 oC and excellent charge transport ability (μh=1.01⨯10^-2 cm²V^-1s^-1 at 4.0⨯10⁵ Vcm-1), is reported in this work. Here, we also accurately predicted the cross-linking temperature and calculated the charge transport parameters of the HTM through molecular dynamic simulation. Finally, incorporating this new HTM into solution-processed OLED, 130.5 cdA^-1 of current efficiency and 37.3% of EQE were achieved. This result is one of the best efficiencies for phosphorescent solution-processed OLED have been reported.
