Abstract

Sm, Er, and Yb complexes containing anionic (4,5,6,7-tetrafluorobenzothiazol-2-yl)-2-(3,4,5,6-tetrafluoro)phenolate (SON^F) and 3-(2-benzothiazol-2-yl)-2-naphtholate (NpSON) and neutral 1,10-phenathroline or 2,2'-bipyridine ligands were synthesized. The structures of complexes Yb(SON^F)₂-(NpSON)(DME)_1.5 (II) and previously synthesized Er(SON^F)₃(DME) (I) were determined by X-ray diffraction (CIF files CCDC nos. 1972769 and 1972770, respectively). Upon excitation by light at λ 405 nm, all complexes showed luminescence of the ligands and Ln³⁺ ions. The OLED devices based on samarium complexes showed moderate intensi metal-centered emission of moderate intensity at a 19 V voltage.

苯并噻唑基苯酚酸酯和-萘酚配体的镧系元素配合物的合成及发光性能

摘要

含有阴离子（4,5,6,7-四氟苯并噻唑-2-基）-2-（3,4,5,6-四氟）酚盐（SON ^F）和3-（2-苯并噻唑）的Sm，Er和Yb络合物合成了-2-基）-2-萘甲酸酯（NpSON）和中性的1,10-菲咯啉或2,2'-联吡啶配体。通过X射线衍射确定复合物Yb（SON ^F）_2-（NpSON）（DME）_1.5（II）和先前合成的Er（SON ^F）₃（DME）（I）的结构（CIF文件CCDC号1972769）和1972770）。在λ405 nm的光激发下，所有配合物均显示出配体和Ln ^3+的发光离子。基于sa络合物的OLED器件在19 V电压下显示出中等强度的中等强度金属中心发射。
