Two luminescent metal-organic-frameworks (LMOFs) constructed by a molecular chromophore [tri(4-pyridylphenyl)amine] (tppa) were synthesized by solvothermal reactions and characterized by single crystal and powder X-ray diffraction, thermogravimetric analysis, optical diffuse reflection, photoluminescence spectroscopy, and internal quantum yield measurements. Both compound 1 [Zn(tppa)(ndc)·(DMF)] and compound 2 [Zn(tppa)(sdc)(NO)·(DMF)·(ACN)] (ndc = 2,6-naphthalenedicarboxylic acid, sdc = (E)-4,4'-(ethene-1,2-diyl)dibenzoic acid, DMF = dimethylformamide, ACN = acetonitrile) exhibit intense yellow emission under blue light (455 nm) excitation. The Commission International de I'Eclairage (CIE) coordinates of 1 (0.42, 0.53) and 2 (0.42, 0.54) are close to that of YAG:Ce (0.41, 0.55) (λ = 455 nm). The two phosphor materials show promise for use in phosphor-converted white LEDs (PC-WLEDs).
通过溶剂热反应合成了由分子发色团三(4-吡啶基苯基)胺构建的两种发光金属有机框架材料(LMOFs)，并通过单晶和粉末X射线衍射、热重分析、光学漫反射、光致发光光谱和内量子产率测量对其进行了表征。化合物1[Zn(tppa)(ndc)·(DMF)]和化合物2[Zn(tppa)(sdc)(NO)·(DMF)·(ACN)](ndc = 2,6-萘二甲酸，sdc = (E)-4,4'-(乙烯-1,2-二基)二苯甲酸，DMF =二甲基甲酰胺，ACN =乙腈)在蓝光(455 nm)激发下均呈现强烈的黄色发射。化合物1(0.42, 0.53)和化合物2(0.42, 0.54)的国际照明委员会(CIE)坐标与YAG:Ce(0.41, 0.55)(λ = 455 nm)的坐标相近。这两种磷光材料有望用于磷光转换白光发光二极管(PC-WLEDs)。
