ABSTRACT Two novel tetra‐ and hepta‐nuclear Ni(II) salamo‐type clusters, [Ni 4 (L) 2 ( μ ‐Cl) 3 ‐OH) (EtOH) ]⋅4CH Cl 1 ) 7 ‐OEt) 6 ] ), were constructed by modulating different anions (Cl − NO ). X‐ray crystallographic researches revealed that cluster is a tetranuclear consisting of symmetric binuclear structure in which chloride ions are involved coordination. Although consists seven ions, three deprotonated 2− parts, two ‐ethoxy groups, six ‐OH anions, coordinated ethanol molecules, it quite rare for large number water molecules to be participate the bridging due alkaline environment. TEM electron scanning displayed distinct shapes. Comparison DFT calculations less chemically reactive more kinetically stable, accordance with analytical results weak interactions, where stronger interaction forces presented, stable molecule is. Finally, comparative analysis UV–Vis, IR, fluorescence spectra carried out.

ABSTRACT A novel salamo‐Co (II) coordination polymer probe CP was synthesized firstly, and its crystal structure, [Co 3 (L) 2 (PTA)(H O) ] n ·4nDMF, determined by X‐ray diffraction analysis. The has a rare aggregation‐induced luminescence enhancement (AIEE) effect. When applied to amino acid detection, it found have high selective recognition of tyrosine. With the increase tyrosine, fluorescent strength enhanced in short period time. In addition, binding ratio Tyr fluorescence titration experiment, detection limit LOD for calculated be 2.57 × 10 −9 M, constant Ka 2.96 5 M −1 . According UV absorption spectrum, FT‐IR spectra, ESI mass spectrometry, DFT calculation, speculated that can bind after adding into solution, triggering FRET ICT effects, resulting increased intensity blue shift, finally achieving specific tyrosine Finally, practical application studied. Through strip test real water sample test, used qualitative quantitative analysis
