moieties was synthesized. Also, tris(2-pyridylmethyl)amine (tpa), bis(2-pyridylmethyl)(2-quinolylmethyl)amine (bpqa), (2-pyridylmethyl)bis(2-quinolyl methyl)amine (pbqa), and tris (2-quinolylmethyl)amine (tqa) were synthesized as terminal ligands of the tetracoordinated tripod. In total, five different dinuclear Co complexes were synthesized from H4BP with various terminal ligands as follows, [Co2(BP)(tpa)2](PF6)2
合成了可以直接连接两个氧化还原活性儿茶酚部分的双儿茶酚,H 4 BP(4,4'-双(3-叔丁基-1,2-儿茶酚))。此外,三(2-吡啶基甲基)胺(tpa)、双(2-吡啶基甲基)(2-喹啉甲基)胺(bpqa)、(2-吡啶基甲基)双(2-喹啉甲基)胺(pbqa)和三(2 -喹啉甲基)胺(tqa)被合成为四配位三脚架的末端配体。总共有五种不同的双核 Co 配合物由 H 4 BP 与各种末端配体合成,如下所示,[Co 2 (BP)(tpa) 2 ](PF 6 ) 2 ( 1 ), [Co 2 (BP)(tpa) 2 ](PF 6 )3 ( 2 )、[Co 2 (BP)(bpqa) 2 ](PF 6 ) 2 ( 3 )、[Co 2 (BP)(pbqa) 2 ](PF 6 ) 2 ( 4 )和[Co 2 ( BP)(tqa) 2 ](PF 6 ) 2 ( 5 )。在配合物 ( 1 )的单电子氧化反应后,配合物
