  • Synthesis, structure and spectral properties of O,N,N coordinating ligands and their neutral Zn(ii) complexes: a combined experimental and theoretical study

    Mononuclear Zn(II) complexes with the general formula [Zn(L)2] have been synthesized in good yields by reacting Zn(OAc)2 with HL in a ratio of 1 : 2 in methanol solvent. Here L is the deprotonated form of 6-[(quinolin-8-ylamino)methylene]cyclohexa-2,4-dienone (HL1), 4-chloro-6-[(quinolin-8-ylamino)methylene]cyclohexa-2,4-dienone (HL2), 4-methyl-6-[(quinolin-8-ylamino)methylene]cyclohexa-2,4-dienone (HL3), 2,4-dimethyl-6-[(quinolin-8-ylamino) methylene]cyclohexa-2,4-dienone (HL4), 2-methoxy-6-[(quinolin-8-ylamino) methylene]cyclohexa-2,4-dienone (HL5). The electronic structures and photophysical properties of the ligands were calculated by DFT and TDDFT methods. The X-ray structure of one complex is reported. The ligands have a strong binding ability [(0.75–15.37) × 104] and ratiometric response to Zn2+ ions. With the addition of Zn2+ ions to the ligands in THF solution a sharp color change is observed visually, and as well a significant enhancement of the fluorescence intensity and the quantum yield for this series occurs. The introduction of other metal ions having biological and environmental effects results in either unaltered or quenched emission intensity. However we observed the sensing property of the ligands strongly depends on the substituent at the ortho position of the phenol group. DFT calculation reveals that the ICT process take place from the salicylaldehyde (donor moiety) to quinoline (acceptor moiety) which is responsible for the enhancement of the fluorescence intensity of ligands after complexation.
    单核Zn(II)配合物,通用公式为[Zn(L)₂],通过在甲醇溶剂中以1:2的比例将Zn(OAc)₂与HL反应,合成得率良好。这里的L是去质子化形式的6-[(喹啉-8-基)亚甲基]环己烯-2,4-二酮(HL1)、4--6-[(喹啉-8-基)亚甲基]环己烯-2,4-二酮(HL2)、4-甲基-6-[(喹啉-8-基)亚甲基]环己烯-2,4-二酮(HL3)、2,4-二甲基-6-[(喹啉-8-基)亚甲基]环己烯-2,4-二酮(HL4)、2-甲氧基-6-[(喹啉-8-基)亚甲基]环己烯-2,4-二酮(HL5)。通过DFT和TDDFT方法计算了配体的电子结构和光物理性质,并报道了一种配合物的X射线结构。配体具有强的结合能力[(0.75–15.37) × 10⁴],以及对Zn²⁺离子的比率响应。当Zn²⁺离子加入到THF溶液中的配体时,观察到明显的颜色变化,同时该系列的荧光强度和量子产率显著增强。引入具有生物和环境作用的其他属离子结果是发射强度不变或被淬灭。然而,我们观察到配体的传感性质强烈依赖苯酚基团的邻位取代基。DFT计算表明ICT过程发生在杨 aldehyde(供体部分)和喹啉(受体部分)之间,这对配合后的配体荧光强度的增强起关键作用。

    Abstract The preparation and magnetic properties of four Fe(II) Schiff-base complexes, [Fe(qsal X ) 2 ] (Hqsal X = N -(8′-quinolyl)-2-hydroxy-5-halogeno-1-salicylaldimine; X = F( 1 ), Cl( 2 ), Br( 3 ), I( 4 )) are reported. X-ray single crystal structure analyses of 1 and 2 reveal that Fe(II) ions in both complexes are coordinated by two qsal X ligands in meridional fashion. Molecular packing of 1
    摘要四种Fe(II)Schiff碱属配合物[Fe(qsal X)2](Hqsal X = N-(8'-喹啉基)-2-羟基-5-卤代-1-杨基亚胺)的制备及磁性能。报告了X = F(1),Cl(2),Br(3),I(4))。对1和2的X射线单晶结构分析表明,两种络合物中的Fe(II)离子均通过两个qsal X配体以子午线的方式进行配位。1的分子堆积表明非平面的qsal F配体通过π-π相互作用与相邻的两个qsal F配体相互作用,而2的分子堆积表明两个平面的qsal F配体通过π-π相互作用彼此相互作用。尽管1的磁性在所有测得的温度范围内均显示出高自旋状态,但2,3和4的χT – T图显示了308 K,341 K和T 1/2时的逐渐自旋交叉行为。分别为340 K

IR spectroscopy confirms that NCS− acts as a counteranion only and that the qsal-X ligand is bound to the FeIII centre. SQUID magnetometric studies reveal stepped hysteretic spin crossover in 1 and 2, which is abrupt in both steps in latter compound. Mössbauer spectroscopic studies
