Singlet oxygen ( 1 O 2 )isofgreat interest because of its potential applications in photodynamic therapy, photooxidation of toxic molecules,a nd photochemical synthesis.H erein, we report novel metallophthalocyanine (MPc) based conjugated microporous polymers (MPc-CMPs) as photosensitizers for the generation of 1 O 2 .T he 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 p-conjugation systems.T heir microporous structure and excellent absorption capability for long-wavelength photons result in the MPc-CMPs showing high efficiency for 1 O 2 generation upon irradiation with 700 nm light, as evident by using 1,3-diphenylisobenzofuran as an 1 O 2 trap.T hese results indicate that MPc-CMPs can be considered as promising photosensitizers for the generation of 1 O 2 .

Light-harvesting antennae are the machinery for exciton pumping in natural photosynthesis, whereas cascade energy transfer through chlorophyll is key to long-distance, efficient energy transduction. Numerous artificial antennae have been developed. However, they are limited in their cascade energy-transfer abilities because of a lack of control over complex chromophore aggregation processes, which has impeded their advancement. Here we report a viable approach for addressing this issue by using a light-harvesting porous polymer film in which a three-dimensional π-network serves as the antenna and micropores segregate multiple dyes to prevent aggregation. Cascade energy-transfer engines are integrated into the films; the rate and efficiency of the energy-funneling engines are precisely manipulated by tailoring the dye components and contents. The nanofilms allow accurate and versatile luminescence engineering, resulting in the production of thirty emission hues, including blue, green, red and white. This advance may open new pathways for realising photosynthesis and photoenergy conversion.

“…Another strategy decorates the porphyrin macrocycle with bulky functional groups to protect the active sites, which is limited by the difficulty of synthesizing these porphyrins [6]. Currently, an additional strategy that has spurred tremendous interest is to incorporate or encapsulate heme into various networks, including metal metalloporphyrins-organic frameworks (MMOFs) [7][8][9][10][11][12][13], covalent metalloporphyrinic frameworks (CMFs) [14][15][16][17] and covalent metalloporphyrinic polymers (CMPs) [18][19][20][21][22]. Among them, covalent metalloporphyrinic polymers (CMPs) are the easiest to design and develop among the three aforementioned classes of materials, they are non-crystalline and have non-uniform pores that are typically somewhat ill-defined.…”
