Looped flow processes are an efficient and versatile tool to synthesize complex macromolecular materials. Especially for light-induced ring-closure reactions, which typically require low concentrations, looped flow processes are critical for upscaling. Here, such a reactor was designed to carry out a photo-induced ring-closure reaction via a photo-enol reaction for the synthesis of cyclic polymers, leading to a reduction of required solvent in the synthesis by over a factor of 40, hence giving access to a more economical and fully scalable process.

通过环流反应器进行 光诱导的闭环†

循环流动过程是合成复杂的高分子材料的有效且通用的工具。尤其是对于通常需要低浓度的光诱导的闭环反应而言，循环流动过程对于扩大规模至关重要。在此，设计这种反应器以通过光-烯醇反应进行光诱导的闭环反应，以合成环状聚合物，从而使合成中所需的溶剂减少了40倍以上，因此得到获得更经济，完全可扩展的过程。
