Enhancement of the fluorescence properties via introducing the tetraphenylethylene chromophores into a novel Mn-organic framework with a rare [Mn4(μ3-OH)2] cluster.

By employing a tetraphenylethylene (TPE)-based tetracarboxylate linker, tetrakis(4-carboxyphenyl)ethylene (H4TCPE), we herein constructed a novel luminescent Mn-MOF based on a rare [Mn4(μ3-OH)2] cluster (SQNU-55). Interestingly, the TPE-based SQNU-55 not only provides a good material for the blue LED device, but also has a better luminescent molecular thermometer for low-temperature detection.
