Stable and efficient deep-blue terfluorenes functionalized with carbazole dendrons for solution-processed organic light-emitting diodes

Deep-blue terfluorenes with highly spectral stability and device efficiency have been successfully developed by functionalizing the backbone with carbazole dendrons, showing a peak EQE of 2.02% and CIE coordinates of (0.16, 0.04) for solution-processed undoped OLEDs.
