摘要

抗菌光催化纳米材料的开发具有重要意义。在这里，我们通过共价有机框架（COFs）的剥离制备了锌卟啉纳米盘。我们通过Zn2+和4-乙基卟啉的简单同时配位，用游离碱卟啉剥离COFs。合成的锌卟啉纳米盘在可见光照射下表现出较高的光催化单线态氧产量，并对大肠杆菌表现出显著的光照射抗菌活性。

Zinc porphyrin covalent organic nanodisks synthesized from covalent organic frameworks and their photocatalytic antibacterial activity

The development of antibacterial photocatalytic nanomaterials is important. Here, we prepared Zn-porphyrin nanodisks by exfoliation of covalent organic frameworks (COFs). We exfoliated COFs with free-base porphyrins by simple simultaneous coordination of Zn²⁺ and 4-ethylphyridine. The synthesized Zn-porphyrin nanodisks exhibited higher photocatalytic singlet oxygen production by visible light irradiation, and showed substantial light-irradiated antimicrobial activity against Escherichia coli.
