Phenoxy-substituted phthalocyanine zinc (PPcZn) was synthesized and used as a photosensitizer to prepare a variety of self-disinfecting films by incorporating it into a cellulose acetate (CA) film at various concentrations. The generation of singlet oxygen (1O2) from the films containing PPcZn irradiated with visible light was detected by a film containing 1,3-diphenylisobenzofuran (DPBF). The rate of 1O2 generation followed a pseudofirst-order kinetic model. Antiviral activity was confirmed under visible light irradiation using Bacteriophage Qβ. The film exhibited superior water resistance, photostability, mechanical strength, and sustained 1O2 production over 6 months under continuous exposure to room light. These data show the promise of this film in real-life applications as self-disinfecting surfaces.

耐用、光学透明和自消毒薄膜的制造和评估

合成苯氧基取代的酞菁锌 (PPcZn) 并将其用作光敏剂,通过将其以不同浓度掺入醋酸纤维素 (CA) 薄膜中来制备各种自消毒薄膜。通过含有 1,3-二苯基异苯并呋喃 (DPBF) 的薄膜检测到含有 PPcZn 的薄膜在可见光照射下产生单线态氧 ( 1 O 2 )。1 O 2生成的速率遵循伪一级动力学模型。使用噬菌体 Qβ在可见光照射下证实了抗病毒活性。该薄膜表现出优异的耐水性、光稳定性、机械强度和持续的1 O 2连续暴露于室内光线下超过 6 个月的生产。这些数据显示了这种薄膜在实际应用中作为自消毒表面的前景。
