《Blue iridium(III) complexes with high internal quantum efficiency based on 4-(pyridin-3-yl)pyrimidine derivative and their electroluminescent properties》 was written by Cheng, Wei; Wang, Li-Ding; Zhou, Yue-Yue; Bian, Zu-Qiang; Tong, Bi-Hai; Liu, Zhi-Wei; Wang, Song. HPLC of Formula: 1193-21-1 And the article was included in Dyes and Pigments in 2020. The article conveys some information:
Three novel highly efficient blue bicyclometalated Ir(III) complexes (Ir1-Ir3) were designed and synthesized with 4-(2,6-difluoropyridin-3-yl)-6-mesitylpyrimidine as primary ligands. The alternation of ancillary ligands had precisely regulated their emitting peaks from sky-blue to deep-blue. These complexes exhibit unimodal emission with PLQYs >90% and lifetimes shorter than 1.1μs. These complexes also show good thermal stability with Td > 320°. The OLED using complex Ir3 as emitter in 13% exhibited a maximum luminous efficiency of 16.9 cd A-1 with a high EQE of 13.0%. The CIE coordinates of this device are (0.15, 0.16), which are close to the standard blue color region. The experimental process involved the reaction of 4,6-Dichloropyrimidine(cas: 1193-21-1HPLC of Formula: 1193-21-1)
4,6-Dichloropyrimidine(cas: 1193-21-1) is a member of organic chlorides. Organic chloride content in crude oil can be detected through specialized laboratory analysis. Care and attention are essential while sampling and testing.HPLC of Formula: 1193-21-1
