  两亲性偶极席夫碱锌（II）配合物中的超分子聚集/解聚

  摘要：

  报道了两亲性席夫碱双（水杨基亚氨基）锌（II）配合物的合成，表征，光学和荧光性质。详细1H核磁共振（NMR），扩散有序光谱（DOSY）NMR，光吸收和荧光光谱研究表明，非配位溶剂中存在聚集体。聚集的程度和类型与非配位溶剂的浓度和极性有关。稀溶液的特征可能在于存在确定的二聚体，而较大的低聚物聚集体可能以较高的浓度形成。观察较大物质形成所需的浓度取决于溶剂的极性。在配位溶剂中或在存在配位物质的情况下，由于与Zn II离子的轴向配位，伴随着1的显着变化，系统发生了完全解聚。1 H NMR和光吸收光谱。用配位剂解聚后，在二氯甲烷溶液中观察到荧光发射显着增强。在双位配体作为配位物种的情况下，证明了确定的2：1超分子结构的形成。总体而言，这些复合物是用于开发新的超分子体系结构和超分子荧光探针的有前途的系统。

  Phase Transition and Vapochromism in Molecular Assemblies of a Polymorphic Zinc(II) Schiff-Base Complex

  摘要：

  This paper reports for the first time the irreversible thermally induced phase transition, accompanied by color change, and the vapochromic behavior of an amphiphilic, Lewis acidic Zn(II) Schiff-base complex, through detailed X-ray diffraction, thermogravimetric analysis and differential scanning calorimetry, and optical absorption studies. The unprecedented irreversible phase transition for such kind of complexes is associated with a thermal, lamellar-to-hexagonal columnar structural transition, which involves a different arrangement of each molecular unit within the assembled structure, H- and J-type aggregates, respectively, responsible for the thermochromic behavior. The vapochromism, investigated either in powder samples or in thermally annealed cast films, is related to the formation of 1:1 adducts upon exposure to vapors of strong Lewis bases and implies dramatic optical absorption variations and naked-eye observation of the change in color from red-brown to red. The chemisorption process is fast, completely reversible, reproducible, and selective for amines. The reversible switching of the chemisorption-desorption process in cast films is demonstrated by successive cycles, amine exposure and subsequent heating, by monitoring the substantial optical absorption changes in the visible region. Vapochromism of this material can potentially be used to detect vapors of volatile amines.

  日期：——

  A designed amphiphilic Schiff-base bis(salicylaldiminato)zinc(II) complex, 1, forms defined aggregates in dilute solutions of non-coordinating solvents. The switching to the monomer can be driven by addition of a coordinating species and involves a dramatic enhancement of the fluorescence emission.
