Trimeric porphyrin H6TP as well as its binuclear Cu2H2TP and trinuclear Cu3TP copper complexes have been prepared. Kinetic features of H6TP and Cu2H2TP complexes formation with copper(II) acetate in acetic acid as well as dissociation kinetics of Cu2H2TP and Cu3TP in acetic acid medium in the presence of sulfuric acid have been studied. 相似文献

The elastoplastic properties (elastic modulus, amplitude-independent damping ratio, microplastic flow stress) of a Ti-26Nb-7Mo-12Zr titanium β alloy are determined using an acoustic resonance method. The effect of the strain during thermomechanical treatment on the structural features of the micro-crystalline alloy and, hence, its elastoplastic properties is analyzed. 相似文献

The possibility of using an approach for the elucidation of the spatial structure of functionalized thiacalix[4]arenes based on the determination the residual dipolar coupling constants between the 1H and 13C nuclei separated by one chemical bond (1
D
CH) in lyotropic liquid-crystalline media (poly--benzyl-L-glutamate and CDCl3) is demonstrated for the first time. This approach was used to distinguish between the cone and 1,3-alternate conformations of 5,11,17,23-tetra-tert-butyl-25,26,27,28-tetrakis(2-oxopropyloxy)-2,8,14,20-tetrathiacalix[4]arene. The results were confirmed by the data from 2D NMR (1H—1H) NOESY experiments for these compounds in an isotropic solvent (CDCl3). 相似文献
