The structures of new compounds were confirmed by elemental analyses, IR, UV, 1H NMR, MS techniques. The Ni2+ of complex compound 4 was in high-spin state by its ESR spectrum.展开更多

The fluorescence spectroscopic titration of the iron complex to the zinc complex was used to examine their behavior of supramolecular self-assembly and the results indicated that the fluorescence quenche of the zinc complex was resulted from the formation of zinc complex/iron complex supramolecular by hy- drongen-bonding..展开更多
