摘要/Abstract

摘要： 环硫脲为配体和亚铜盐在溶剂热条件下进行反应，通过调整配体与亚铜盐的摩尔比以及亚铜盐中的阴离子，得到4种环硫脲亚铜配合物：1-Cu（TU）I、2-Cu（TU）₂I、3-[Cu（TU）₂]（BF₄）和4-[Cu（TU）₂]（PF₆）。对这4个配合物的光物理性质进行测定。通过激光倍频效应发现化合物1的SHG效应的响应活性是KDP的1.1倍。在392或335 nm下激发，化合物3和4在室温下分别在517和520 nm处产生具有较高量子产率的固体磷光发射。

Abstract: Cyclic thiourea copper(I) complexes, 1-Cu(TU)I, 2-Cu(TU)₂I, 3-[Cu(TU)₂](BF₄), and 4-[Cu(TU)₂](PF₆), were successfully prepared by solvothermal method. By adjusting the molar ratio of the ligand to the cuprous salt and the anion in the cuprous salt, we got four coordination complexes and characterized their structures by X-ray single crystallography. The photophysical properties of these four complexes were measured. Complex 1 exhibited modest SHG response of 1.1 times response of potassium dihydrogen phosphate(KDP). Under excitation at either 392 or 335 nm, complexes 3 and 4 showed the phosphorescence at 517 and 520 nm, respectively, and high quantum yields in solid state at room temperature.

Key words: cyclic thiourea, copper(I) complexes, solid state phosphorescence, second-order nonlinear optical properties
