제목 Synthesis of bipolar host materials for thermally activated delayed fluorescence devices
초록 In this work, 3-(furo[2,3-b:5,4-b’]dipyridin-3-yl)-N,N-diphenylaniline (3TPAPFP) and 4-(furo[2,3-b:5,4-b’]dipyridin-3-yl)-N,N-diphenylaniline (4TPAPFP) were synthesized as thermally activated delayed fluorescence (TADF) host materials for green fluorescent organic light emitting diodes (OLEDs). Two bipolar hosts combined triphenylamine electron donor and pyrido[3’,2’:4,5]furo[2,3-b]pyridine (PFP) electron acceptor with high electron affinity. Green fluorescent OLEDs were fabricated by doping 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene in these host materials and maximum quantum efficiencies of 3TPAPFP and 4TPAPFP devices were 22.1 % and 6.6 %, respectively.
