摘　　要：为解决光致抗菌织物上光敏剂(PS)聚集诱导引起的猝灭(ACQ)效应,通过在棉织物上原位合成一种含二苯甲酮结构的酰胺基多孔有机聚合物(POP-CF),并吸附孟加拉玫瑰红(RB),制备成抗菌棉织物(RB@POP-CF)。结果表明:POP-CF的BET比表面积为28.914 m2/g,孔径为3.407 nm;其对RB主要以物理吸附为主,最大吸附量为5.22 mg/g;RB在POP-CF孔中的分散吸附显著降低了ACQ效应,在模拟阳光照射下,二苯甲酮结构与RB分子协同高效地产生活性氧(ROS),达到4.18 mg/L;10 min内可杀死99.88%的大肠埃希菌和99.99%的金黄葡萄球菌。In order to solve the aggregation-caused quenching(ACQ)effect of photosensitizer(PS)on the pho⁃to-induced antibacterial fabric,an amide-based porous organic polymer(POP-CF)containing benzophenone structure is synthesized in-situ on the cotton fabric,and Rose Bengal(RB)is adsorbed to prepare the antibacte⁃rial cotton fabric(RB@POP-CF).The results show that the BET specific surface area of POP-CF is 28.914 m2/g,and the average pore size is 3.407 nm.The adsorption of RB is mainly attributed to the physical adsorption,and the maximum adsorption capacity reaches about 5.22 mg/g.The dispersion adsorption of RB in POP-CF pores significantly reduces the ACQ effect of RB.Under the simulated sunlight irradiation,the benzophenone struc⁃ture and RB molecule synergistically and efficiently produce reactive oxygen species(ROS),reaching about 4.18 mg/L;99.88%of Escherichia coli and 99.99%of Staphylococcus aureus can be killed in 10 min.
