Abstract

Imidazolium ionic side-group-containing fluorene-based conjugated polyelectrolytes (CPEs) with different π-conjugated structures, poly[(9,9-bis(8′-(3-methyl-1-imidazolium)octyl)-2,7-fluorene)-alt-2,7-(9,9-dioctylfluorene)] dibromide (F8im-Br) and poly[(9,9-bis(8′-(3-methyl-1-imidazolium)octyl)-2,7-fluorene)-alt-(benzo(2,1,3)thiadiazol-4,8-diyl) dibromide (F8imBT-Br), are synthesized and utilized as an electron injection layer (EIL) in green-emitting F8BT polymer light-emitting diodes (PLEDs). Both CPE EIL devices significantly outperform Ca cathode devices; 17.9 cd A-1 (at 3.8 V) and 16.6 lm W-1 (at 3.0 V) for F8imBT-Br devices, 11.1 cd A-1 (at 4.2 V) and 9.1 lm W-1 (at 3.4 V) for F8im-Br devices, and 7.2 cd A-1 (at 3.6 V) and 7.0 lm W-1 (at 3.0 V) for Ca devices. Importantly, unlike the F8im-Br EIL devices, F8imBT-Br PLEDs exhibit much faster electroluminescence turn-on times (
