The 2,2'-bipyridyl moieties lining the channels of two designer metal-organic frameworks (MOFs), UiO-bpydc and Eu-bpydc (bpydc is 2,2'-bipyridine 5,5'-dicarboxylic acid), recognize and pre-concentrate metal ion analytes and, in the case of Eu-bpydc, transfer energy to the Eu(3+) centers, to provide highly sensitive luminescence sensors for transition metal ions.
两种定制金属有机框架（MOF），即UiO-bpydc和Eu-bpydc（bpydc为2,2'-联吡啶5,5'-二羧酸）通道内的2,2'-联吡啶部分，能够识别并预富集金属离子分析物，并且在Eu-bpydc的情况下，将能量转移至Eu(3+)中心，从而为过渡金属离子提供高灵敏度的发光传感器。
