Singlet oxygen is a potent oxidant with major applications in organic synthesis and medicinal treatment. An efficient way to produce singlet oxygen is the photochemical generation by fullerenes which exhibit ideal thermal and photochemical stability. In this contribution we describe readily accessible ML nanospheres with unique binding sites for fullerenes located at the windows of the nanospheres. Up to four C can be associated with a single nanosphere, presenting an efficient method for fullerene extraction and application. Depending on the functionality located on the outside of the sphere, they act as vehicles for O generation in organic or in aqueous media using white LED light. Excellent productivity in O generation and consecutive oxidation of O acceptors using C⊂[PdL], C⊂[PdL] or fullerene soot extract was observed. The methodological design principles allow preparation and application of highly effective multifullerene binding spheres.
单线态氧是一种强氧化剂，在有机合成和药物治疗中有重要应用。产生单线态氧的一种有效方法是富勒烯的光化学生成，富勒烯具有理想的热和光化学稳定性。在本贡献中，我们描述了易于获得的 ML 纳米球，其具有位于纳米球窗口处的富勒烯的独特结合位点。多达四个 C 可以与单个纳米球结合，提供了一种有效的富勒烯提取和应用方法。根据位于球体外部的功能，它们可用作在有机或水介质中使用白色 LED 光生成 O 的载体。观察到使用 C⊂[PdL]、C⊂[PdL]或富勒烯烟尘提取物，在 O 生成和随后的 O 受体氧化中具有优异的生产力。所采用的方法设计原则允许制备和应用高效的多富勒烯结合球。
