The fluorescent light-collecting material can realize the spectral conversion and energy accumulation, which is an effective strategy to improve the photon utilization efficiency and the reaction rate in the photochemical reaction process. The existing light-collecting materials are mostly based on solid matrix, which is difficult to combine with the fluid reaction, as well as poor dispersion and low fluorescence quantum efficiency. Most importantly, each material with certain emission needs specific preparation. This proposal is to prepare high efficient fluorescent microfluidic light-collecting material based on fluid medium, which has obvious adjustable features in micro-chemical composition and macroscopic spatial structure. It is easy to be coupled with photochemical reaction by microreactor structure design. This work is expected to open a new way for the study of photochemical reactions in confined spaces. The research contents include: the chemical composition control and performance study of high efficient fluorescent microfluidic; the spatial distribution of fluorescent microfluidic and light field controlled by the microreactor structure; the combination of fluorescent microfluidic and micro reactor and their regulation function on photochemical reaction. This proposal is expected to explore a simple method for preparing high performance fluorescent microfluidic materials, and contribute to the application of light-collecting materials in the field of microreactor photochemistry.
