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.
