本文报道了手性配体2,5-二(4,5-蒎烯-2-吡啶)吡嗪(L)及其铼配合物[Re(CO)3Cl(L)].DMF的合成与表征。X射线单晶衍射分析表明配体L晶体为单斜P21空间群,而配合物[Re(CO)3Cl(L)].DMF晶体为正交P212121空间群。配合物[Re(CO)3Cl(L)].DMF中铼原子与配体中的2个氮原子、3个羰基中的碳原子以及1个氯原子配位。CD谱和VCD谱测试表明,配体和配合物都表现出光学活性。受光激发时,配体和配合物分别在420和650 nm处发光。配体和配合物都具有二阶非线性光学性质,其二阶非线性光学效应分别为尿素的0.4和0.3倍。
In this paper, the synthesis and characterization of 2, 5-bis (4,5-pinene-2-yl) pyrazine (L) and its rhenium complex [Re (CO) 3Cl (L) . X-ray single crystal diffraction analysis showed that the ligand L crystal is monoclinic P21 space group, while the complex [Re (CO) 3Cl (L)] DMF crystal is orthorhombic P212121 space group. Complex [Re (CO) 3Cl (L)]. The rhenium atom in DMF is coordinated with two nitrogen atoms in the ligand, three carbon atoms in the carbonyl group and one chlorine atom. CD spectra and VCD spectra showed that both ligands and complexes showed optical activity. When excited by light, the ligand and the complex emit light at 420 and 650 nm, respectively. Both ligands and complexes have second-order nonlinear optical properties, and their second order nonlinear optical effects are 0.4 and 0.3 times that of urea respectively.
