Singlet oxygen ((1) O2 ) is of great interest because of its potential applications in photodynamic therapy, photooxidation of toxic molecules, and photochemical synthesis. Herein, we report novel metallophthalocyanine (MPc) based conjugated microporous polymers (MPc-CMPs) as photosensitizers for the generation of (1) O2 . The rigid microporous structure efficiently improves the exposure of the majority of the MPc units to oxygen. The MPc-CMPs also exhibit an enhanced light-harvesting capability in the far-red region through their extended π-conjugation systems. Their microporous structure and excellent absorption capability for long-wavelength photons result in the MPc-CMPs showing high efficiency for (1) O2 generation upon irradiation with 700 nm light, as evident by using 1,3-diphenylisobenzofuran as an (1) O2 trap. These results indicate that MPc-CMPs can be considered as promising photosensitizers for the generation of (1) O2 .
