找到对抗细菌感染或污染的方法，同时将我们对抗生素的依赖降至最低，是本世纪最紧迫的需求之一。虽然使用UV-C光和强氧化剂，如漂白剂，仍然是消除细菌表面污染的有效方法，但这两种方法都存在严重的健康和/或环境危害。具有内在光动力学活性的材料(即，材料在光激发下将分子氧转化为单线态氧等活性氧物种的能力)与可见光磁谱内的光一起工作，可以提供一种安全得多的替代方案。在这里，我们提出了一种新的定制的钼簇合物(Bu4N)2[{Mo6I8}(CF3(CF2)6COO)6]，它既能有效地在光照射下产生单线态氧，又能与以透氧性好而闻名的氟聚合物(F-32L)兼容。因此，(Bu4N)2[{Mo6I8}(CF3(CF2)6COO)6]/F-32L混合物经过溶液处理后，得到了光滑且纤维状的均匀薄膜，在可见光照射下对四种常见病原菌表现出了较高的光诱导抗菌活性。因此，这些材料具有潜在的应用范围，从抗菌涂层到滤膜和空调，以防止细菌感染的传播。
Finding methods that fight bacterial infection or contamination, while minimising our reliance on antibiotics is one of the most pressing needs of this century. Although the utilisation of UV-C light and strong oxidising agents, such as bleach, are still efficacious methods for eliminating bacterial surface contamination, both methods present severe health and/or environmental hazards. Materials with intrinsic photodynamic activity (i.e. a material's ability upon photoexcitation to convert molecular oxygen into reactive oxygen species such as singlet oxygen), which work with light within the visible photomagnetic spectrum could offer a significantly safer alternative. Here we present a new, bespoke molybdenum cluster (Bu4N)2[{Mo6I8}(CF3(CF2)6COO)6], which is both efficient in the generation of singlet oxygen upon photoirradiation and compatible with the fluoropolymer (F-32L) known for its good oxygen permeability. Thus, (Bu4N)2[{Mo6I8}(CF3(CF2)6COO)6]/F-32L mixtures have been solution-processed to give homogenous films of smooth and fibrous morphologies and which displayed high photoinduced antibacterial activity against four common pathogens under visible light irradiation. These materials thus have potential in applications ranging from antibacterial coatings to filtration membranes and air conditioners to prevent spread of bacterial infections.
