将未保护的单核pyr修饰的(双吡啶基氨基甲基)甲基苯酚铜配合物固定在多壁碳纳米管(MWCNT)电极上,并在表面形成双核双(μ-酚基)配合物。与可逆氢电极相比,这些配合物具有12.7 mA cm -2的高氧还原反应活性和0.78 V的起始电势。与具有较大基团的单核复合物相比,这些复合物具有更高的活性,这是由于在MWCNT上有利于早期形成双核催化物质而引起的。

diaminopyrene of the ligands H2LP1 and H2LP2. In addition, the introduction of the pyrene motifs in 1 and 2 enhanced their activity toward DNA and as effective antitumor drugs, although the biochemical mechanism of the latter effect is currently under investigation. These complexes represent interesting examples of how to promote an increase in the activity of traditional artificial metal nucleases by
本文中,我们报道了两种双核Fe III Zn II配合物[Fe III Zn II LP1](1)和[Fe III Zn II LP2](2)的合成和表征,其中LP1和LP2是包含一个和两个的共轭体系基分别通过二胺-HN(CH 2)4 NH–间隔基连接至众所周知的N 5 O 2-供体H 2 L配体(H 2 L = 2-双[((2-吡啶基甲基)氨基甲基] -6-[(2-羟基苄基)(2-吡啶基甲基)]氨基甲基} -4-甲基苯酚)。络合物[Fe III Zn为了比较的目的,在本研究中包括II L1](3),其中将H 2 L修饰为H 2 L1,并且在末端酚基上连接有羰基。1配合物1和2在固态和溶液中均具有令人满意的特性。乙腈溶液中1和3的扩展X射线吸收精细结构数据表明,以3的固态观察到的多重桥接结构保留在溶液中。1和2的电位和UV-Vis滴定示出了质子化氨基基团和配位水分子之间的静电相互作用显著减小在p

additional basic amine groups in the sidechain enhances DNA binding due to electrostatic interactions. Those compounds containing only a single basic benzylic amine bind similarly to DNA. Only the presence of bulky sidechains appears to decrease the DNA interactions in the compounds examined. Although antitumor activity is seen for (1-pyrenylmethyl)amino alcohols, useful antitumor activity in the series

copper complexes were designed to be immobilized at multiwalled carbon nanotube (MWCNT) electrodes and form dinuclear bis(μ-phenolato) complexes on the surface. These complexes exhibit a high oxygen reduction reaction activity of 12.7 mA cm–2 and an onset potential of 0.78 V versus reversible hydrogen electrode. The higher activity of these complexes compared to that of mononuclear complexes with bulkier
