A pH-triggering supramolecular antibacterial photosensitizer was constructed by host-guest interaction between a water-soluble porphyrin photosensitizer and carboxylatopillar[5]arene (P[5]). The formation of the supramolecular complex not only improves the biocompatibility of the photosensitizer, but also enhances antibacterial efficacy by pH-triggering dissociation under the low pH bacterial microenvironment.
通过水溶性卟啉光敏剂与羧酸柱[5]芳烃(P[5])之间的主客体相互作用,构建了一种 pH 触发的超分子抗菌光敏剂。超分子复合物的形成不仅提高了光敏剂的生物相容性,而且还通过在低 pH 细菌微环境下 pH 触发解离增强了抗菌功效。
