简单介绍


ossila材料CzBN  的详细介绍

Due to the conjugation, CzBN is relatively red shifted in absorption and emission when compared to DABNA-1. CzBN has an absorption band at around 470 nm and narrow emission band at 479 nm with FWHM of 30 nm in dilute dichloromethane solution and PLQYs of 87%.

A solution processed sky-blue multiresonance TADF OLED device, based on 5 wt.% CzBN in a CzAcSF host, exhibited a maximum current efficiency of 24.3 cd/A, a power efficiency of 15.9 lm/W, and an external quantum efficiency of 14.7%. This is a device efficiency improvement when compared to the vacuum-deposited OLEDs based on DABNA-1.
