Abstract

ABSTRACT Dinuclear Ni(II), Cd(II) and Hg(II) complexes have been prepared from photoluminescent salicylaldimine tetra-coordinated [N4O4] donor compartmental Schiff base ligand. The photophysical and mesogenic properties of the compounds are investigated. The compounds are characterized by elemental analyses, mass, 1HNMR, FT-IR and UV–visible spectroscopy. The complexes adopted distorted square planar geometry. The ligand and Ni complex exhibit monotropic thermal transition in DSC thermogram whereas Cd or Hg complexes are non-mesogenic. All the complexes displayed blue emission at ∼450 nm.

镍(II)、镉(II)和汞(II)的同双核四齿希夫碱配合物:合成、光物理和中间相研究

摘要以水杨醛二胺四配位[N4O4]施主区室希夫碱配体为原料制备了Ni(II)、Cd(II)和Hg(II)双核配合物。研究了化合物的光物理性质和介生性质。通过元素分析、质量、1HNMR、FT-IR和紫外可见光谱对化合物进行了表征。该复合体采用了扭曲的方形平面几何。配体和Ni配合物在DSC热图上表现为单向热转变，而Cd或Hg配合物则是非介生的。所有配合物在~ 450 nm处显示蓝色发射。

期刊介绍： Phase Transitions is the only journal devoted exclusively to this important subject. It provides a focus for papers on most aspects of phase transitions in condensed matter. Although emphasis is placed primarily on experimental work, theoretical papers are welcome if they have some bearing on experimental results. The areas of interest include: -structural phase transitions (ferroelectric, ferroelastic, multiferroic, order-disorder, Jahn-Teller, etc.) under a range of external parameters (temperature, pressure, strain, electric/magnetic fields, etc.) -geophysical phase transitions -metal-insulator phase transitions -superconducting and superfluid transitions -magnetic phase transitions -critical phenomena and physical properties at phase transitions -liquid crystals -technological applications of phase transitions -quantum phase transitions Phase Transitions publishes both research papers and invited articles devoted to special topics. Major review papers are particularly welcome. A further emphasis of the journal is the publication of a selected number of small workshops, which are at the forefront of their field.
