| Abstract: |
Nanoflakes of an aminoacid-based chiral coordination polymer (CP), [Cu 2 (tyr) 2 (bipy)] n , were synthesized successfully in the presence of surfactant, as evidenced by the XRD and SEM results. UV–vis absorption spectrometry and fluorescence spectrometry were used to investigate the optical properties of the CP, which was found to be mainly attributed to the ligands, while the forming of the CP caused only slight change. On the other hand, Cu(II) ions acted as electrocatalytic active sites of the CP, as evidenced by cyclic voltammetry. The CP also showed good performance in the electrochemical sensing of H 2 O 2 : sensitivity of 85.6 mA mol −1 L cm −2 , linear range of 1.0×10 −5 –7.69×10 −3 M, detection limit of 1.0×10 −5 M ( S / N =3), and fast response in mere 5 s.
