Electrospinning is a cost-effective and efficient method of producing polymeric nanofibre films. The resulting nanofibres can be produced in a variety of structures, including monoaxial, coaxial (core@shell), and Janus (side-by-side). The resulting fibres can also act as a matrix for various light-harvesting components such as dye molecules, nanoparticles, and quantum dots. The addition of these light-harvesting materials allows for various photo-driven processes to occur within the films. This review discusses the process of electrospinning as well as the effect of spinning parameters on resulting fibres. Building on this, we discuss energy transfer processes that have been explored in nanofibre films, such as Förster resonance energy transfer (FRET), metal-enhanced fluorescence (MEF), and upconversion. A charge transfer process, photoinduced electron transfer (PET), is also discussed. This review highlights various candidate molecules that have been used for photo-responsive processes in electrospun films.
静电纺丝是一种经济高效的生产聚合物纳米纤维膜的方法。所得的纳米纤维可以多种结构形式生产，包括单轴、同轴（核壳）和双轴（并列）。所得纤维也可以作为各种光收集组件（如染料分子、纳米粒子和量子点）的基质。这些光收集材料的添加允许在膜内发生各种光驱动过程。本综述讨论了静电纺丝的过程以及纺丝参数对所得纤维的影响。在此基础上，我们讨论了在纳米纤维膜中已经探索过的能量转移过程，如Förster 共振能量转移（FRET）、金属增强荧光（MEF）和上转换。还讨论了电荷转移过程，即光诱导电子转移（PET）。本综述强调了各种已用于静电纺丝膜中光响应过程的候选分子。
