A series of D3 (Fe(II), Ru(II), Zn(II), Hg(II)) and D2d (Cu(I), Ag(I), Zn(II)) octupolar metal complexes featuring different functionalized bipyridyl ligands has been synthesized, and their thermal, linear (absorption and emission), and nonlinear optical (NLO) properties were determined. Their quadratic NLO susceptibilities were determined by harmonic light scattering at 1.91 microm, and the molecular
一系列具有不同官能化联吡啶的D3(Fe(II),Ru(II),Zn(II),Hg(II))和D2d(Cu(I),Ag(I),Zn(II))八极金属络合物已经合成了配体,并确定了它们的热,线性(吸收和发射)和非线性光学(NLO)性质。它们的二次NLO磁化率由1.91微米的谐波光散射确定,分子的超极化率(beta0)值在200-657 x 10(-30)esu范围内对于八面体络合物和70-157 x 10(-30) esu用于四面体配合物。八面体锌(II)配合物1 e包含4,4'-低聚亚苯基亚乙烯基官能化的2,2'-联吡啶,对于八极衍生物(lambdamax = 482 nm,beta1.91(1 e)= 870 x 10(-30)esu,beta0(1 e)= 657 x 10(-30)esu)。在本文中,我们证明了光学和非线性光学(NLO)特性受配合物的对称性,配体的性质(供体端基和pi连
