建立了一套有机光反应微反应系统，在微空间中考察了非对映体区分光敏化反应、有机物的光催化氧化还原反应和胺的N-烷基化反应过程。这些模型反应进行得非常迅速，具有相当大的光子效率，因为微反应器的光反应的一些独特的属性，如更高的空间照明均匀性和更好的光穿透整个反应器的深度，和大的表面积与体积比相比，大规模的间歇式反应器。这些结果表明，微反应系统的有机光反应的可行性。
A microreaction system for organic photoreactions was developed, and the processes of diastereo-differentiating photosensitized reaction, photocatalytic oxidation and reduction of organic compounds, and amine N-alkylation were examined in microspace. These model reactions proceeded very rapidly with considerably large photonic efficiencies because of some distinct properties of microreactors for photoreactions, such as higher spatial illumination homogeneity and better light penetration through the entire reactor depth, and large surface-to-volume ratio in comparison with large-scale batch reactors. These results suggest feasibility of microreaction systems on organic photoreactions.
