| description | A [O,N] bidentate π-expanded ligand system, (E)-1-(<i>n</i>-octylimino)methylpyren-2-ol (<b>2</b>), was newly synthesized via a six-step synthesis from pyrene. The ligand <b>2</b> reacts with [PtCl<sub>2</sub>(PhCN)<sub>2</sub>] in chlorobenzene and the presence of a base at reflux for 2 h under the formation of (<b>2(Pt)</b>) complex with a yield of 70%. The molecular structure of (<b>2(Pt)</b>), studied by common spectroscopic methods and X-ray diffraction, shows a square planar geometry with a trans-configuration of the ligands. The molecular structure, absorption spectra, electrochemical properties, and phosphorescence characteristics of the (<b>2(Pt)</b>) complex are discussed, emphasizing the comparison with those of the previously reported Pt complex (<b>1(Pt)</b>) containing the isomeric ligands of <b>2</b>, (E)-2-(<i>n</i>-octylimino)methylpyren-1-ol. The DFT calculations of the two Pt complexes are carried out and exhibit a clear explanation of the relationship between their physico-chemical characteristics. |
