Efficiency loss mechanism of hyper-fluorescent organic light-emitting diodes was studied by comparing two sensitizers with different molecular structures and a design strategy of the sensitizer was suggested. Examination of two sensitizers with a 3,6

Recently, organic thermally activated delayed fluorescence (TADF) emitters have attracted a great deal of attention because they can theoretically realize 100% internal quantum efficiency. Many TADF emitters have been developed since the first demons

The fabrication of organic light-emitting diodes (OLEDs) composed of multi-layered structure through a solution-based process suffers from the dissolution of the preformed lower parts during the coating of upper layers. To prevent this problem during

A surface initiated oxidative coupling method was developed as a crosslinking approach of hole transport materials for solution processed organic light-emitting diodes. The surface initiated crosslinking method was better than bulk oxidative crosslin
