A hollow-core photonic crystal fibre (HC-PCF), guided by photonic bandgap effects or anti-resonant reflection, offers strong light confinement and long photochemical interaction lengths in a microscale channel filled with a solvent of refractive index lower than that of glass (usually fused silica). These unique advantages have motivated its recent use as a highly efficient and versatile microreactor for liquid-phase photochemistry and catalysis. In this work, we use a single-ring HC-PCF made from a high-index soft glass, thus enabling photochemical experiments in higher index solvents. The optimized light-matter interaction in the fibre is used to strongly enhance the reaction rate in a proof-of-principle photolysis reaction in toluene.
一种空心光子晶体光纤（HC-PCF），通过光子带隙效应或抗共振反射来引导，在折射率低于玻璃（通常是熔融二氧化硅）的溶剂填充的微通道中提供强的光限制和长的光化学反应长度。这些独特的优势促使其最近被用作高效且多功能的微反应器，用于液相光化学和催化。在这项工作中，我们使用了一种由高折射率软玻璃制成的单环 HC-PCF，从而能够在更高折射率的溶剂中进行光化学实验。光纤中的优化光物质相互作用用于在甲苯的光解反应中强烈提高反应速率，这是一个原理验证实验。
