A fully conjugated system 4 consisting of two 2-aza-21-carbaporphyrin (NCP) subunits bridged by dipyrrin was synthesized by a highly selective condensation of 3-pyrrole-NCP 2 with aryl aldehydes. The free base 4 as well as its silver(III) complex 5 exhibited flexibility of the bridge allowing synergetic binding of Ag , thus leading to a mixed-valence tetraporphyrinic assembly consisting of eight silver atoms which was characterized both in the solid state and in solution. Binding of chiral acid by 4 and 5 was shown by observation of an induced optical activity of the adducts.
通过3-吡咯-N-碳杂卟啉2与芳基醛的高度选择性缩合反应,合成了一种由二吡咯桥联两个2-氮杂-21-碳杂卟啉(NCP)亚基组成的完全共轭体系4。游离碱4及其银(III)配合物5表现出桥联的灵活性,允许银协同结合,从而形成由八个银原子组成的混合价四卟啉组装体,该组装体在固态和溶液中均得到了表征。通过观察加合物的诱导光学活性,表明4和5对手性酸具有结合作用。
