Özet

An imidazole and biphenyl-appended cyclotriphosphazene (2, L) and its 1D copper(II) coordination polymer (3) which formulated as [L-2(CuCl2)](n) were synthesized. The structure of 2 was determined by elemental analysis and different spectroscopic tecqniques. The crystal structures of 2 and 3 were defined by single-crystal X-ray crystallography. The copper atom in complex 3 was in a slightly distorted octahedral geometry which coordinated by four monodentate imidazole nitrogen and two chlorine atoms. The magnetic properties of 3 was discussed via ESR spectroscopy. The thermal properties of 2 and 3 were investigated by thermogravimetric analysis (TGA). The photophysical and electrochemical properties of 2 and 3 were evaluated by UV-Vis-fluorescence spectroscopies and cyclic (CV)-square wave (SWV) voltammetric techniques. In addition, HOMO-LUMO energy levels were calculated according to UV-Vis absorption and CV measurements. (C) 2020 Elsevier B.V. All rights reserved.
