tetrazole acid Synthesis

Title: tetrazole acid Synthesis and properties of Author: Xiu-Qing Zhang Degree-granting units: Nankai University Keywords: tetrazole acid;; crystal structure;; magnetic properties;; fluorescence properties;; biological activity Abstract: Carboxylic acid containing heterocyclic ligand, carboxy-metal ions with a variety of ways you can bond, while a number of heterocyclic nitrogen atom may be
With metal ions, it can be used for synthesis, Magnetic lifter structure and properties of various complexes. Using the solution method, with twenty-two synthesized
Material. By IR, elemental analysis, X-ray diffraction and other means, a more systematic study of which a crystal structure,
And apply the UV spectrum, fluorescence spectroscopy, CD spectroscopy, viscosity analysis and agarose gel electrophoresis and other means to study some of the complexes
Chemical nuclease activity, measured some of the complex nature of solid fluorescent and magnetic properties. This paper is divided into the following three parts:
Chapter I: The solution synthesized http://www.999magnet.com/products/131-magnetic-lifter tetrazolium -5-- acid complexes 13 and 12 resolution crystal structure of complexes. Measured with
Compounds (1) - (4) and (7) - (9) of the magnetic properties. Complexes (1) - (4) are anti-ferromagnetic material; for complexes (7) - (9), because
Strong rare-earth ion spin-orbit coupling, the magnetic properties is more complex. Using spectroscopy method and studied the complex viscosity (1), (4)
, (5), (10), (11) with DNA and found that five complexes are of moderate intensity are inserted with DNA. The use of condensate
Gel electrophoresis of the complexes (1), (4), (5), (10), (11) for cutting the role of plasmid pBR 322, was found with five
Things have nuclease activity, may to some extent cut DNA. Measured at room temperature, the complexes (13) of solid fluorescent in the 338 nm
Under the conditions of excitation wavelength in the fluorescence emission at 519 nm. Chapter II: The solution synthesized tetrazolium -5-- acid
6 complexes and their crystal structure analysis. The complex was determined (15) - (19) of the magnetic properties. Complexes (15) is an antiferromagnetic
Magnetic material. Complexes (16) - (19) of the central metal ion are Pr (Ⅲ), Nd (Ⅲ), Sm (Ⅲ), Gd (Ⅲ). For complex
Material (16) and (17) we use the magnetic nature of the ligand-field approximation is calculated, calculations show that these two complexes are also anti-ferromagnetic. With
Compounds (18) is Sm (Ⅲ) one-dimensional chain polymer, Sm (Ⅲ) ions between the antiferromagnetic interaction exists. Complexes (19) is a
Dual-core anti-ferromagnetic material Gd. Chapter III: The solution synthesized tetrazolium -5-- Ethyl 3 complexes and analysis of its
Crystal structure. At room temperature, the complex was determined (20) and (21) of solid fluorescent quality. Complexes (20) in the 352 nm excitation wavelength conditions
, In the fluorescence emission at 378 nm. Complexes (21) in the excitation wavelength of 336 nm under the conditions in the fluorescence emission at 396 nm. Determine
Complexes (22) of the magnetic properties and the use of spectroscopic methods, viscosity and gel electrophoresis method of the complexes (22) interaction with DNA
Use, found ways to insert the complex with DNA, has nuclease activity, to some extent cut DNA. Degree Year: 2009
