Functional materials with multiple properties are urgent to be explored to reach high requirements for applications nowadays. In this work, a new multifunctional one-dimensional (1D) chain compound [N(C3H7)4][Cu(ohpma)]·H2O 1 (ohpma = deprotonated N-(2-hydoxyphenyl)oxamic acid) exhibiting both 1D antiferromagnetic and nonlinear optical properties, which are both originated from the same polar [Cu(C8H4NO4)]
迫切需要探索具有多种性能的功能材料以满足当今应用的高要求。在这项工作中,一种新的多功能一维(1D)链化合物[N(C 3 H 7 ) 4 ][Cu(ohpma)]·H 2 O 1(ohpma =去质子化的N- (2-羟基苯基)肟酸)具有一维反铁磁和非线性光学性质的材料,均源自相同极性的[Cu(C 8 H 4 NO 4 )]磁性单元,已通过室温蒸发成功合成。(ohpma) 3−配体的双多齿性质,具有受约束的三齿和二齿配位位点,可传导 Cu 2+离子以不同的几何形状配位,并沿c轴形成一维链,这些链进一步被 [N(C 3 H 7 ) 4 ] +阳离子。并且一维磁链还表现出非中心对称的极性排列。非线性光学研究表明极性化合物1表现出明显的二次谐波产生(SHG)效率,部分态密度的计算表明1的SHG效率主要来源于极性化合物[Cu(C 8 H 4 NO 4 ) ] 磁性单位。此外,磁化率在 70 K 附近显示出一个宽的最大值,具有J/k
