Abstract
1,6-Diaminohexane (DAHX) was used as template for construction of new host-guest coordination network; (a) (3)[(Cu-3(CN)(3))(2)center dot(DAHX)], 1. This supramolecular coordination polymer (SCP) consists of 3D-(Cu-3(CN)(3))(2) network based on distorted tetrahedral copper(I) atoms. The extended structure of SCP 1 contains a new two-fold Cu-3(A mu(3)-CN)(4) units which are assembled in unique way to adopt wide voids capable to accommodate the long chain diamine molecules. The structure of 1 was investigated by elemental analysis, IR and H-1-NMR spectroscopy, thermogravimetric analyses and X-ray single crystal diffraction. The SCP 1 acts as effective catalyst for degradation of methylene blue (MB) dye using H2O2 as oxidant. Photoluminescence probing technology was used as a sensitive probe for detecting (OH)-O-center dot radicals and a reaction mechanism has been suggested utilizing the redox properties of H2O2.
