in blue organic light-emitting diodes requiring hightripletenergy host. They showed hightripletenergy above 2.79 eV and acted as the electron transport type host based on the strong electron deficiency. The mixture of the CNDBF1 and CNDBF2 hosts with a hole transport type 3,3′-di(9H-carbazol-9-yl)-1,1′-biphenyl host performed as the exciplex host of a blue phosphor and accomplished high external

hosts for long lifetime in sky‐blue thermally‐activated delayed fluorescence (TADF) organiclight‐emitting diodes (OLEDs) were investigated by synthesizing four hosts with zig‐zag‐type backbone structure for hightripletenergy. The four hosts had two CN units at different positions of the zig‐zag‐type backbone structure and two dibenzofuran units through either the 2 or 4‐position of dibenzofuran. The
