Aluminum-based coordination polymers, MIL-110(Al) nanotubes, were successfully prepared from a mixed solution of methanol and ethanol with the volume ratio of 10 : 10 at room temperature in the absence of any template or surfactant; AlCl and sodium 1,3,5-benzenetricarboxylate (NaBTC) were employed as the initial reactants. The composition, structure, and morphology of the as-obtained nanotubes were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive spectrometry (EDS), thermogravimetric analysis (TGA), and inductively coupled plasma atomic emission spectroscopy (ICP-AES). It was found that the initial reaction medium played a crucial role in the formation of nanotubes. More importantly, MIL-110(Al) nanotubes could be fabricated into lanthanide-functionalized luminescent materials by a simple post-treatment process. The as-obtained luminescent materials could emit red, green, and white light, which have potential applications in the fields of sensing, biomedicine, labeling, and color display. Furthermore, the PL of the as-obtained luminescent materials could be selectively quenched by Fe ions, which can be used as probes for the detection of Fe ions.
铝基配位聚合物MIL-110(Al)纳米管是在室温下，以体积比为10∶10的甲醇和乙醇混合溶液为原料，在无任何模板或表面活性剂的情况下成功制备的；以AlCl和1,3,5-苯三甲酸钠(NaBTC)作为起始反应物。通过X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、能谱分析(EDS)、热重分析(TGA)和电感耦合等离子体原子发射光谱(ICP-AES)对所得纳米管的组成、结构和形貌进行了表征。发现初始反应介质在纳米管的形成中起关键作用。更重要的是，通过简单的后处理工艺可以将MIL-110(Al)纳米管制备成镧系功能化发光材料。所得发光材料可发出红、绿、白光，在传感、生物医学、标记和彩色显示等领域具有潜在应用。此外，所得发光材料的光致发光(PL)可被Fe离子选择性猝灭，可用作检测Fe离子的探针。
