The results showed that HL as a bidentate ligand coordinated with transition metal ions to form four-coordination complexes. The antibacterial activity was studied by using the filter scraps diffusion method, and the results indicated that the ligand and the complexes had a low bacteriostatic activity against S. Aureu, P. Aeruginosa and E. Coli. The low in vitro antitumor activity of the title complexes was also observed by using MTT method against KB, A2780, Bel7402 and HELF.展开更多

The equilibrium constants of the aggregation of the metal porphyrin and the equilibrium constant of the π\|π coordination with phenothoroline have been measured by using UV\|Vis titration method. The results show that the equilibrium constants decrease in the order of K \-\{CuP\}> K \-\{NiP\}> K \-\{ZnP\}. The vitro anti\|tumor activities of the dibutyltin(Ⅳ) metal porphyrinate has some relation with the ability of aggregation and coordination with ligand of the metal porphyrin.展开更多
文摘以天然生物大分子鞣花酸(EA)为有机配体,Zn(CH_3COO)_2·2H_2O为锌源,N-甲基吡咯烷酮为溶剂,在室温下经超分子自组装形成金属生物大分子配合物(Zn EA)前驱体,再经碳化制备了分级多孔碳球.研究了不同碳化温度和酸洗处理过程对多孔碳球的结构、形貌、比表面积和电化学储能的影响.结果表明,在惰性气氛下,1000℃下碳化制备的多孔碳材料(C-Zn EA-1000)的比表面积高达1238 m^2/g,最可几孔径分布约为4 nm;在6 mol/L KOH电解液中,扫描速率为5 m V/s时比电容为216 F/g.当扫描速率由5 m V/s增加到100 m V/s时,其比电容保持率为84.67%,显示了优异的倍率特性.在1 A/g的电流密度下,经过5000周充放电循环后比电容的损失仅为3%,具有优异的循环稳定性.
