Synthesis, structures and optical properties of a series of zinc(II) complexes bearing salophen ligands derived from 3,5-di-tert-butyl-2-hydroxybenzaldehyde
The photophysical and spectral characteristics of a series of Zn(II)-salophen complexes ZnL1–ZnL6 were systematically analyzed using various analytical techniques. The SC-XRD results of ZnL1 and ZnL4-ZnL6 show that in the crystals of the four complexes, each central metal Zn(II) has a coordination number of five, bonded to the ligand through four donor atoms O^N^N^O and an ethanol molecule. In ethanol at room temperature, all complexes displayed a strong emission at 530–550 nm, characterized by a fluorescence quantum yield of 25–71 % with a significant Stokes shift of 115–129 nm. The complexes fluoresce weaker in the solid state with Φ = 0.4–1.1 % with a red shift in wavelength compared to that in ethanol. The lifetime measured using time-correlated single photon counting showed longer lifetime in solid state (0.37–0.59 ns) than in ethanol (0.14–0.33 ns). Quantum chemical calculations were performed using DFT and TD-DFT methods to obtain structural parameters and the optical properties of complexes.
期刊介绍:
Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews.
Topics covered include:
• chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies;
• synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs);
• reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models;
• applications of inorganic compounds, metallodrugs and molecule-based materials.
Papers composed primarily of structural reports will typically not be considered for publication.
