Graphical Abstract

Selective photoreaction under shielded conditions. We have developed near-infrared light-activatable phthalocyanine catalysts. In this image, the colors of the cars show the kind of light. The visible wavelengths (rainbow colors) are blocked (traffic cones); only NIR light (the gray vehicle) can pass to interact with the phthalocyanine catalyst. After this photoreaction, singlet oxygen (as 1O2) and product are generated. More information can be found in the Full Paper by T. Furuyama, H. Nakai, et al. (DOI: 10.1002/chem.202103223).
