The photosensitizer system based on cationic COF carrier with the loading tetraminoporphyrin and its combined antibacterial effect

The 2D covalent organic framework COF TGTp was synthesized and TAPP deposited on it via π–π interactions to form TAPP/COF TGTp . Excellent antibacterial effect against both Gram-positive and Gram-negative bacteria was achieved with good biosafety.
