Its white light consists of comparably uncommon monomeric blue and common excimeric yellow phosphorescence associated with Cu3(pyrazolate)3, achieved by multiple non-covalent interactions involving chlorine.文章链接：C9CC00716

Yuan Tian,aZhao-Yang Wang,*aShuang-Quan Zang, *a Dan Li *band Thomas C. W. Mak a,cABSTRACT:A series of AIE active cyclic trinuclear complexes (Au3, Ag3, and Cu3) have been successfully prepared and elucidated by X-ray crystallography. These complexes showed excellent AIE properties and their quantum yields (QYs) were significantly increased compared to those of the free ligands. The remarkable solution induced AIE activity in atom-precise coinage metal complexes is still scarce, and this work op

Heng Zeng, Mo Xie, Yong-Liang Huang, Yifang Zhao, Xiao-Jing Xie, Jian-Ping Bai, Meng-Yan Wan, Rajamani Krishna, Weigang Lu,* and Dan Li*ABSTRACT:Porous materials that can undergo pore-structure adjustment to better accommodate specific molecules are ideal for separation and purification. Here, we report a stable microporous metal-organic framework, JNU-1, featuring onedimensional diamond-shaped channels with a high density of open metal sites arranged on the surface for the cooperative binding o

Hong Cai, Weigang Lu, Chen Yang, Ming Zhang, Mian Li, Chi-Ming Che, and Dan Li*ABSTRACT:Luminescent ratiometric thermometers (LRTs) based on the emission intensity ratio with self-reference functions guarantee a temperature sensing of fast response, high precision, and excellent spatial resolution. For monitoring temperature at the cellular level, the use of metal-organic frameworks (MOFs) as probes, especially biocompatible ones, is still in its nascency. By employing a biological MOF, Zn3(benz

Shun-Ze Zhan,*,† Wei Chen,† Weigang Lu,‡ Ji Zheng,‡ Fei Ding,† Tong Feng,† and Dan Li*,‡ABSTRACT:Three Cu3Pz3-based isostructural complexes (Cu3L3)2(CuX)2(labeled as 1-ClO4, 1-NO3, and 1-Br, where X = ClO4-, NO3-, and Br-, respectively) were prepared by solvothermal reactions of an angular bifunctional pyridyl-pyrazole ligand, 4-(pyridin-4′-ylthio)-3,5-dimethyl-1Hpyrazole (HL), with Cu(ClO4)2, Cu(NO3)2, and CuBr, respectively. Pyrazolate (Pz) groups are highly specific to form planar trinuclear

Chong-Wei Ding,†,‡Wenzhi Luo,‡Jie-Yi Zhou,†,‡ Xin-Jie Ma,‡Guang-Hui Chen,‡ Xiao-Ping Zhou,*,†and Dan Li*ABSTRACT:Metalloenzymes are powerful biocatalysts that can catalyze particular chemical reactions with high activity, selectivity, and specificity under mild conditions. Metal-organic frameworks (MOFs) composed of metal ions or metal clusters and organic ligands with defined cavities have the potential to impart enzyme-like catalytic activity and mimic metalloenzymes. Here, a new metal−organic
