Advances in Deep Blue Emitters for Highly Efficient and Long Lifetime Organic Light Emitting Diodes
오형윤 한국공업화학회 2019 한국공업화학회 연구논문 초록집 Vol.2019 No.0
Here, we present new efficient deep-blue emitters developed by using proper molecular design for high efficiency and long lifetime organic light emitting diodes (OLEDs). These emitters not only show high photoluminescence quantum yield but also demonstrate very small solvatochromic effect with pure deep blue color and excellent thermal properties. The OLEDs with these blue emitters exhibited high external quantum efficiency, appropriate CIE color coordinates with narrow full width half maximum (FWHM) and most importantly long operational lifetime compared to those of previously reported emitters.
