Outline of Final Research Achievements

In this research, we designed some microflow devices for various photoreactions. We elucidated that the fabrication of the appropriate set-up is very important for the efficient photoreaction proceeding, in addition to only utilizing microreactors. Furthermore, the slug flow mode, which is the specific flow mode in microreactors, enabled to improve the photoreaction efficiency (conversion, yield, and productivity) compared to that not only in batch reactors but also in microreactors under normal one-layer conditions. Additionally, we validated both on-chip spectrophotometry and optical rotation with CMOS image sensors for measuring photoreactions on time. As a result, we achieved to monitor the asymmetric photoreaction proceeding on time from the data of both the transmittance and optical rotation.
