摘要：
A very stable and blue luminescent complex Zn(bbp)Cl-2 (bbp: 2,6-bis(benzimidazolyl)pyridine) was synthesized. X-ray crystal structural analysis for the complex revealed that there are intermolecular pi(...)pi interactions in the solid state. The fluorescence properties for this complex were studied. The similar devices with the structure of [ITO/CuPc(31 nm)/NPB(80 nm)/[Zn(bbp)Cl-2] (or L) (85 nm)/LiF15/Al] were constructed to investigate their electroluminescent performance. Both the complex and the ligand can be fabricated as blue-emitting materials. The complex shows emission peak at 555 nm, electroluminescent efficiency 0.017 cd A(-1) and turn-on voltage 7 V, compared to 470 nm, 0.036 cd A(-1) and 9 V for the ligand. (c) 2004 Elsevier Ltd.
