Abstract

In this manuscript, we report on the performance of organic light-emitting diodes with remote metallic contact using N,N'-ditridecylperylene-3,4,9,10-tetracarboxylic diimide (PTCDI-C₁₃H₂₇) as well as perfluorohexyl-sustituted quaterthiophenes (DHF-4T) as the electron-transport material. Both materials exhibit high electron field-effect mobility. An electron mobility of 0.123 cm²/Vs is demonstrated for DHF-4T. The wide optical bandgap of DHF-4T allows reduction of the light absorption in the region of interest compared to PTCDI-C₁₃H₂₇. In this way an external quantum efficiency of 0.25% could be obtained. This is a factor of 10 larger than in PTCDI-C₁₃H₂₇ based devices.
