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.
