Non-doped red or blue electroluminescent materials based on fluorenyl-triarylamines with fumaronitrile or fluorene bridge

► Triarylamines of fumaronitrile or fluorene bridge as red or blue fluorescent dyes. ► The compounds act as both emitters and hole-transporting materials in devices. ► The efficiency of the non-doped red device is 3.5 cd/A with CIE of (0.67, 0.31). ► The efficiency of the non-doped blue device is 1.04 cd/A with CIE of (0.18, 0.19). ► The centric core in the triarylamines tunes emission color effectively.
