Ag(I) 促进的 5,15-二芳基 Zn(II)-卟啉的氧化介观-介观偶联反应是我们在光合反应中心的合成方法过程中偶然发现的。基于该反应，合成了多种直接连接和融合的卟啉阵列，包括线性内消旋-内消旋连接卟啉阵列、风车形和网格状卟啉阵列、内消旋-β单连接二卟啉、β-β连接二卟啉、内消旋-β双连接（融合）二卟啉和寡卟啉、内消旋-内消旋β-β双连接（融合）二卟啉和内消旋β-β-β-β三联（融合）二卟啉。考虑到其高区域选择性以及易于扩展到大卟啉阵列，5,15-二芳基 Zn(II)-卟啉的内消旋偶联反应是有利的，正如通过离散内消旋-内消旋连接的 128 聚体和聚（5,15-卟啉基）的合成所证明的那样。最后，用DDQ-Sc(OTf)(3)氧化末端苯基封端的内消旋-内消旋连接的锌卟啉，得到π-共轭扁平卟啉带。据我们所知，内消旋-内消旋连接的 128 聚体是最长的人造离散分子，而卟啉带 12 聚体是最广泛共轭的卟啉阵列，3500 cm(-1) 处的最低电子带峰证明了这一点。
The Ag(I)-promoted oxidative meso-meso coupling reaction of 5,15-diaryl Zn(II)-porphyrin was serendipitously found in the course of our synthetic approaches towards photosynthetic reaction centers. Based on this reaction, a variety of directly linked and fused porphyrin arrays have been synthesized, including linear meso-meso-linked porphyrin arrays, windmill- and grid-shaped porphyrin arrays, meso-beta singly linked diporphyrins, beta-beta linked diporphyrins, meso-beta doubly linked (fused) diporphyrins and oligoporphyrins, meso-meso beta-beta doubly linked (fused) diporphyrins, and meso-meso beta-beta-beta-beta triply linked (fused) diporphyrins. The meso-meso coupling reaction of 5,15-diaryl Zn(II)-porphyrins is advantageous considering its high regioselectivity as well as its ease of extension to large porphyrin arrays as is demonstrated by the synthesis of a discrete meso-meso-linked 128-mer and poly(5,15-porphyrinylene). Finally, the oxidation of end-phenyl capped meso-meso-linked zinc porphyrins with DDQ-Sc(OTf)(3) gave pi-conjugated flat porphyrin tapes. To the best of our knowledge, the meso-meso linked 128-mer is the longest man-made discrete molecule, and the porphyrin tape 12-mer is the most extensively conjugated porphyrin array, as evinced by the lowest electronic band peak at 3500 cm(-1).
