双水杨醛缩苯二胺锌荧光量子效率的研究

Study on fluorescence property and fluorescence quantum yields of bis(salicyladimine) zine(Ⅱ) complexes

研究了4种双水杨醛缩苯二胺锌配合物的荧光性能,测定了它们的荧光量子效率.结果表明,不同取代基对双水杨醛缩苯二胺锌的荧光效率有不同影响:配合物中供电子取代基使双西佛碱金属配合物的荧光效率增强,吸电子取代基使双西佛碱金属配合物的荧光效率降低.为设计合成具备高荧光量子效率的发光材料提供了依据.

Schiff base complexes are A,B,C,D.Their fluorescence property has been studied and their fluorescence quantum yields have been determined.It is illuminated that different substituents have different effect on fluorescence quantum yields.Electron-donating substituents improve the fluoresunce quantum yields of Schiff base complexes,while electron-withdrawing substituents descend the fluorescence quantum yields of Schiff base complexes.
