摘要
The bis-imidazolium salt 1,4-bis[N-(9'-anthracenyl-methyl)imidazoliumyl]butane hexafluorophosphate ((LH2)-H-1 center dot(PF6)2) and its N-heterocyclic carbene (NHC) silver(I) macrometallocycle [((LAg)-Ag-1)(2)](PF6)(2) (1) have been prepared and characterized. 18-Membered macrometallocycle of 1 is formed via two ligands (L-1) and two silver(I) ions. The selective recognition of m-dinitrobenzene (DNB) using 1 as a host was studied on the basis of fluorescence titrations,H-1 NMRtitrations, HRMS spectra and IR spectra.The results indicate that 1 can distinguish effectively m-dinitrobenzene with other aromatic compounds.
