| Abstract: | 3,8-Bis(4-methoxyphenyl)-1,10-phenanthroline (L) has been found to show high sensitivity toward Zn2 + than other competitive metal ions, where Zn2 +-selective chelation-enhanced fluorescence response at 461 nm is attributed to the formation of a 1:1 metal–ligand complex. In addition, two single-crystal structures of ligand L have been included with the same metal and ligand ratio of 1:1, namely one mononuclear Zn(II) complex Zn(L)Cl2] (1) and one 1D Cd(II) coordination polymer Cd(L)(NO3)2]n (2). |
