A self-coupling reaction of 3-amino-5-bromo-BODIPY under Buchwald–Hartwig amination conditions has led to the synthesis of nitrogen-bridged cyclic BODIPY tetramer, pentamer, and hexamer. Subsequent oxidation of these BODIPY oligomers with DDQ in the presence of alkali metal ions gave 1, 2, and 3, which show high affinities towards alkali metal ions. Expanded azaporphyrins 1 and 2 display global aromaticity.

由多个 BODIPY 单元组成的扩展氮杂卟啉：全球芳香性和对碱金属离子的高亲和力

3-氨基-5-溴-BODIPY 在 Buchwald-Hartwig 胺化条件下的自偶联反应导致了氮桥环 BODIPY 四聚体、五聚体和六聚体的合成。随后在碱金属离子存在下用 DDQ 氧化这些 BODIPY 低聚物得到1、2 和 3 ，它们对碱金属离子显示出高亲和力。扩展的氮杂卟啉1和2显示出整体芳香性。
