Shun-Ze Zhan, *a Jing-Hong Li, aGuo-Hui Zhang, a Xiao-Wei Liu, aMian Li, aJi Zheng, bSeik Weng Ngcand Dan Li *bABSTRACT:A luminescent edge-interlocked heteroleptic metallocage based on Cu3(pyrazolate)3 was prepared through a ligand replacement reaction from a homoleptic metallocage and a new ligand. Its structure was confirmed by XRD and MALDI-TOF mass spectrometry. Theoretical calculations revealed the new ligand was evidently responsible for the bathochromic shift of the optimal excitation. Th

The p-acidity/basicity of cyclic trinuclear units (CTUs): from a theoretical perspective to potential applications
32次浏览
Ji Zheng, Hu Yang, Mo Xie and Dan Li *ABSTRACT:Cyclic trinuclear units (CTUs) based on Au(I), Ag(I) and Cu(I) cations, featuring near planar nine-membered coordination rings, represent an important class of metal-organic p-acids/bases with highly adjustable p-acidity/basicity. Their superior p-acidity/basicity coupled with Lewis-acidic and metal···metal bonding sites offers excellent attraction for a wide range of acidic/basic species, and usually followed by noticeable changes of luminescence o

Yan Yan Li+,[a]Tian-Ya He+,[a, b] Rui-Rong Dai,[a]Yong-Liang Huang,[a] Xiao-Ping Zhou,*[a] Tianfeng Chen,*[a] and Dan Li*[a]ABSTRACT:A family of gyroidal metal–organic frameworks (STUs) composited with transition metal ions and bi-imidazolate ligands (BIm) were prepared and applied as both Lewis base and acid catalysts. Benefiting from the intrinsic basicity of the ligands and the Lewis acidic sites of the open metal centres, the STUs materials show excellent catalytic activities as Lewis base f

pH-Modulated luminescence switching in a Eu-MOF: rapid detection of acidic amino acids

Yifang Zhao, Meng-Yan Wan, Jian-Ping Bai, Heng Zeng, Weigang Luand Dan Li *ABSTRACT:Single-emission probes have demonstrated limited application in complex systems because the signal can be easily disrupted by many non-analyte factors. MOF-based luminescence sensors have been widely explored due to their structural abundance and tunability. Herein, we report a dual-emitting Eu-MOF (1), constructed by Eu(NO3)3and 2,6-naphthalenedicarboxylic acid (H2NDC), exhibiting a specific luminescence switchi

Liang Liang,‡bDong Luo, ‡aTao Zuo,aXiao-Ping Zhou *aand Dan Li *ABSTRACT:A series of cubic cobalt-imidazolate cages have been successfully synthesized via subcomponent self-assembly in different solvents under solvothermal conditions. The homovalent CoII and mixed-valence CoIII,II-imidazolate cages are assembled with control over the mixed solvent ratio of N,N-diethylformamide/ethanol, respectively.文章链接:c9cc02083g.pdf

A chemopalette strategy for white light by modulating monomeric and excimeric phosphorescence of a simple Cu(I) cyclic trinuclear unit

Hu Yang, ‡abJi Zheng,‡a Su-Kao Peng,aXiao-Wei Zhu, aMeng-Yan Wan,aWeigang Luaand Dan Li *aABSTRACT:Room-temperature white phosphorescence with a quantum yield(QY) of 35.6% and a CIE coordinate of (0.33, 0.37) is observed for Cl-a, the crystal of cyclic Cu3(4-chloropyrazolate)3. 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
