At present, in view of the current situation of the analytical chemistry in applied chemistry major, such as the traditional teaching mode, meagre teaching methods, and complicated teaching contents, Chuzhou University, an applied university, is taken as an example to make corresponding teaching exploration and reform of analytical chemistry course. Firstly, the new version of the syllabus was revised, which improved the course design and task distribution, strengthened the construction of the curriculum connotation, and implemented the undergraduate talent training program. Secondly, the typical problems in the actual life and industry are organically integrated into the curriculum ideological and political content. Through combining theory with actual situation, it applied what had learned to solve practical problem and established morality and cultivate people in a subtle way. Finally, the learning platform is used to break the traditional teaching mode, complete the closed-loop interaction between teachers and students, mobilize the enthusiasm of students, improve the teaching method and improve the teaching quality.展开更多
A novel pyrazole derivative ligand, BTA（BTA = bis-（4-ethoxy-phenyl）-[4-（tripyrazol-1-yl-methyl）-phenyl]-amine）, was synthesized and fully characterized by 1H-NMR, MALDI-TOF-MS spectra and single-crystal X-ray di...A novel pyrazole derivative ligand, BTA（BTA = bis-（4-ethoxy-phenyl）-[4-（tripyrazol-1-yl-methyl）-phenyl]-amine）, was synthesized and fully characterized by 1H-NMR, MALDI-TOF-MS spectra and single-crystal X-ray diffraction analysis. It crystallizes in triclinic, space group P1, with a = 11.827（1）, b = 16.000（2）, c = 16.527（2）A, α = 108.510（1）, β = 91.116（5）, γ = 101.734（1）°, V = 2894.5（6） A3, Z = 1, Dc = 1.262 g/m^3, F（000） = 1162, Μr = 545.63, μ = 0.083 mm-1, the final R = 0.0728 and w R = 0.2213 for 7541 observed reflections with I 〉 2（I）. The structural analysis revealed that three pyrazole units are attached to the same carbon atom connected with bis-（4-ethoxy-phenyl）-phenyl-amine group. UV-vis spectral features of the ligand in various solutions were explained by time dependent density functional theory（TD-DFT）. It was also found that the ligand（BTA） exhibits an exclusively selective and sensitive response toward Fe3＋ using UV-vis spectroscopic method.展开更多
