Description
Summary:Although the organic light-emitting devices (OLEDs) encompassing TVs, smartphones, and wearable devices, etc. already have been commercialized, there is still room to pursue material improvements in efficiency and cost-effectiveness. Organic light-emitting materials have experienced the development of the three generation system, it is timely to summary the recent advances and the remaining challenges of the materials as well as their corresponding devices. Special attention is mainly concentrated on describing the blue material structures and related electroluminescence (EL) device performances (the maximum EQE data, Commission Internationale de l’Eclairage (CIE) coordinates, and efficiency roll-off). This short review will show the current governing hotspots concerning OLEDs in academic fields, which may pave the way for next step of industrial application.
