We report aromaticity switching from a 6π pyridine ring to a 22π macrocyclic ring of 3-oxypyripentaphyrin(0.1.1.1.0). This system has potential applications in photodynamic therapy owing to macrocyclic aromaticity being selectively induced by protecting group removal and strong absorption bands produced in the NIR region especially in methanol.

苄基单元的脱保护诱导具有强NIR吸收的3-氧吡啶并卟啉（0.1.1.1.0）的22π芳族大环。

我们报告的芳香性从6π吡啶环转换为3-oxypyripentaphyrin（0.1.1.1.0）的22π大环。由于通过保护基团的去除和在NIR区域产生的强吸收带（特别是在甲醇中）选择性诱导大环芳族化合物，该系统在光动力疗法中具有潜在的应用。
