摘要

采用各种分析技术系统地分析了一系列Zn(II)-salophen配合物ZnL1-ZnL6的光物理和光谱特性。ZnL1和ZnL4-ZnL6的SC-XRD结果表明,在这4种配合物的晶体中,中心金属Zn(II)的配位数均为5,通过4个给体原子O^N^N^O和1个乙醇分子与配体结合。在室温乙醇中,所有配合物在530-550 nm处显示出强发射,荧光量子产率为25 - 71%,Stokes位移为115-129 nm。该配合物在固体状态下的荧光较弱,Φ = 0.4 - 1.1%,波长红移与乙醇相比。使用时间相关单光子计数测量的寿命显示,固态(0.37 ~ 0.59 ns)比乙醇(0.14 ~ 0.33 ns)的寿命更长。利用DFT和TD-DFT方法进行量子化学计算,得到配合物的结构参数和光学性质。

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.
