Abstract :
Complexes M(NpOON)n and M(NpSON)n (NpOON = 3-(2-benzoxazol-2-yl)-2-naphtholate, NpSON = 3-(2-benzothiazol-2-yl)-2-naphtholate, M = Li, Sc, Sm, Eu, Gd, Tb, Dy) were prepared by the reactions of silylamides M[N(SiMe3)2]n (n = 1, 3) with corresponding O,N-chelating ligand. For the synthesis of zinc complexes Zn(NpOON)2 and Zn(NpSON)2 diethylzinc was used. Li, Zn and Sc naphtholates exhibited strong green electroluminescence. The OLED device based on Sc(NpOON)3 showed luminance 8780 cd/m2 (12 V) – the highest value among the devices prepared with organoscandium luminophores.
