Metal-organic frameworks (MOFs) are crystalline porous materials that include metal ions linked together into periodic structures via organic ligands. MOFs that contain lanthanide ions are a new class of visible and near-IR luminescent materials, suitable for a broad range of applications. For example, the MOF framework afforded by 2,5-dimethoxy-1,4-phenylene)di-2,1-ethenediyl]bis-carboxylate is associated with unusually long luminescence lifetimes. Thus, a complex of this ligand with a lanthanide provides a sharp emission profile, coupled with a comparatively long signal lifetime, for an unusually high luminescence. More generally, lanthanide-MOF systems exhibit several advantages that are ideal for barcoded materials, due to the photophysical attributes of lanthanide cations and the well-defined organization of the MOF structure.
金属有机框架(MOFs)是由金属离子通过有机配体链接成周期结构的晶体多孔材料。包含镧系离子的MOFs是一种新型的可见光和近红外发光材料,适用于广泛的应用。例如,由2,5-二甲氧基-1,4-苯基)二-2,1-乙烯二酸的MOF框架与异常长的发光寿命相关。因此,这种配体与镧系离子的复合物提供了一个锐利的发射谱线,加上相对较长的信号寿命,产生了异常高的发光强度。更普遍地说,镧系-MOF系统具有多种优点,非常适合于条形码材料,这是由于镧系阳离子的光物理属性和MOF结构的良好定义组织。
