| Abstract |
A novel Zn(II) coordination polymer, namely, [Zn(Hpzdc)(ncp)]n (1) was synthesized by the reaction of zinc(II), pyrazole-3,5-dicarboxylic acid (H3pzdc), and neocuproine (ncp) at ambient temperature. The single-crystal X-ray diffraction analysis revealed that each tetrahedral Zn(II) center is assembled by Hpzdc
linker exhibiting 1D zigzag-like chain coordination polymer. The interchain hydrogen bonding and p-p
stacking interactions stabilize a 3D supramolecular framework of 1. The photoluminescence in solid state
and suspension of 1 exhibits blue emission at 418 nm. Moreover, the ethanolic suspension of 1 can be
used to selectively detect acetone through the luminescent quenching (turn-off) process within 30 s.
Compound 1 displays low detection limit (LOD) of 0.016 vol% without the interference of competitive solvents. Also, compound 1 can be reusable for three times. |
