Embodiment

[0015] Embodiment: Zn(NO 3 ) 2 ·6H 2 O (29.7mg, 0.1mmol), 2,2'-biquinoline (25.6mg, 0.1mmol), 2,2'-biphenyldiacid (24.0mg, 0.1mmol) and NaN 3 (13.2mg, 0.2mmol) was added to a mixed solvent of 12mL methanol and secondary deionized water (volume ratio 1:1), sealed in a 25mL stainless steel container lined with tetrafluoroethylene, heated to 140°C and kept for 3 days, and then cooled slowly to room temperature. Filter, ether washes filter cake, after drying in air, just obtains colorless massive crystal, based on Zn(NO 3 ) 2 ·6H 2 The calculated yield of O is about 61%. The substance is insoluble in water and other organic solvents.

Abstract

The invention discloses a 2, 2'-biquinoline azide-zinc metal complex and a preparation method and application thereof. The preparation method utilizes a solvothermal synthesis method and comprises that reactants such as zinc nitrate hexahydrate, sodium azide and 2, 2'-biquinoline undergo a reaction according to a mole ratio of 1: 2: 1 in a solvent which is a mixed solution of an appropriate amountof 2, 2'-diphenic acid, methanol and water at a temperature of 130-150 DEG C, the reaction system is kept at the temperature for 3 days and then is cooled to the room temperature, the reaction product is filtered, then the filter cake is washed through diethyl ether so that the 2, 2'-biquinoline azide-zinc metal complex monocrystal C18H12N8Zn is obtained. The complex has a single-molecule structure. Through a hydrogen bond and pai...pai aromatic ring stacking, the three-dimensional supramolecular structure is obtained. Through ultraviolet excitation, strong fluorescence is produced at 418 nm.The 2, 2'-biquinoline azide-zinc metal complex is a novel fluorescent material and can be used for preparing fluorescent emitting devices.

Description

technical field [0001] The invention relates to the field of metal organic complexes, in particular to a 2,2'-biquinoline azide zinc metal complex, a preparation method thereof, and an application of the complex in luminescent materials. Background technique [0002] Metal-organic complexes have attracted the research attention of many chemical and material science workers because of their excellent properties in gas storage, capture, drug delivery, bioimaging, and optical, electrical, and magnetic functional materials. This type of compound uses organic matter as the only or main ligand, and is constructed into metal-organic materials with specific functions through coordination bonds, other intermolecular forces and metal ions. This material combines the diversity, flexibility and modifiability of organic ligand coordination forms with the variability of metal ion coordination ability, endowing it with unique properties different from traditional inorganic or organic mater...
