Sequential excitation energy and electron transfer (ET) are ubiquitous pathways for converting solar to chemical in photosynthesis. Mimicking this unique process synthesis is promising yet still a big challenge. Herein, taking photosynthesis as an inspiration, we demonstrate interesting pathway oxygen reduction hydrogen peroxide (H2O2), important valuable commodity chemical. The proposed route was verified on biomimetic photocatalyst, i.e., aluminum porphyrin metal–organic framework nanosheet (Al–TCPP). Experimental investigations theoretical calculations reveal that the dioxygen molecule first converted highly active singlet intermediate through (EET) then reduced H2O2 via photogenerated electrons with barrier over Al–TCPP. Consequently, Al–TCPP shows 32 times higher evolution rate than of pristine TCPP counterpart, wherein mainly exists. This study presents paradigm mimic photosynthetic sequential electron-transfer improved chemicals.

Covalent organic frameworks (COFs) are appealing photocatalysts for toxic chemical degradation. Great efforts have been devoted to regulate the photocatalytic performance of COFs by tuning their building blocks, but relationship between COF linkage and photochemical properties has rarely explored. Herein, we report synthesis characterisation a novel aminal-linked porphyrinic COF, namely Por-Aminal-COF. Por-Aminal-COF (0.25 mol %) showed excellent activity toward detoxification sulfur mustard simulant with half-life (t1/2 ) 5 min, which is far lower than that traditional imine-linked Por-COF =16 min). Transient absorption spectroscopy indicated aminal linkages facilitated intersystem crossing process. Thus, higher triplet-state generation efficiency compared Por-COF, consequently promoting activation oxygen molecular singlet oxygen.
