Lv, Jie;Lu, Yinfu;Wang, Jinglan;Zhao, Feng;Wang, Yibo;He, Haifeng;Wu, Yaqian research published 《 Schiff base-type copper(I) complexes exhibiting high molar extinction coefficients: Synthesis, characterization and DFT studies》, the research content is summarized as follows. The three Schiff base-type Cu(I) complexes [Cu(POP)(NN̂)]PF6, NN̂ = N,N-diphenyl-4-(6-((phenylimino)methyl)pyridin-3-yl)aniline (P1), N-((5-(4-(diphenylamino)phenyl)pyridin-2-yl)methylene)naphthalen-2-amine(P2), N-((5-(4-(diphenylamino)phenyl)pyridin-2-yl)methylene)adamantan-1-amine (P3), were prepared and characterized. The photophys. properties of these Cu(I) complexes is tuned by the addition of different substituents such as Ph, naphthyl and adamantanyl groups into the backbone of Schiff base ligand. The resulting complexes exhibit high absorption ability in the visible region with molar absorptivities of up to 3 7400 M-1 cm-1. The emissions in CH2Cl2 solution are at 551-552 nm with lower quantum yields of 1.1-2.0% and short-lived excited lifetimes of 2.78-3.09 ns for all the complexes at room temperature The photophys. properties were further explained by DFT and TDDFT methods.
