Developing efficient artificial photocatalysts for the biomimetic photocatalytic production of molecular materials, including medicines and clean energy carriers, remains a fundamentally technologically essential challenge. Hydrogen peroxide is widely used in chemical synthesis, medical disinfection, energy. However, current industrial production, predominantly by anthraquinone oxidation, suffers from hefty penalties toxic byproducts. Herein, we report hydrogen protonation-induced...
Two-dimensional (2D) covalent organic frameworks (COFs) are an emerging class of promising 2D materials with high crystallinity and tunable structures.

Two-dimensional covalent organic frameworks (2D COFs) represent a family of crystalline porous polymers with long-range order and well-defined open nanochannels that hold great promise for electronics, catalysis, sensing, energy storage. To date, the development highly conductive 2D COFs has remained challenging due to finite π-conjugation along lattice charge localization at grain boundaries. Furthermore, transport mechanism within framework remains elusive. Here, time- frequency-resolved...
Abstract Two-dimensional conjugated polymers (2DCPs), composed of multiple strands linear with extended in-plane π-conjugation, are emerging crystalline semiconducting for organic (opto)electronics. They represented by two-dimensional π-conjugated covalent frameworks, which typically suffer from poor π-conjugation and thus low charge carrier mobilities. Here we overcome this limitation demonstrating two phthalocyanine-based poly(benzimidazobenzophenanthroline)-ladder-type 2DCPs (2DCP-MPc, M...
The development of efficient and low-cost catalysts is essential for photocatalysis; however, the intrinsically low photocatalytic efficiency as well difficulty in using recycling photocatalysts powder morphology greatly limit their practical performance. Herein, we describe quasi-homogeneous photocatalysis to overcome these two limitations by constructing ultrastiff, hierarchically porous, photoactive aerogels conjugated microporous polymers (CMPs). CMP exhibit density but high stiffness...
Two-dimensional conjugated metal–organic frameworks (2D c-MOFs) have attracted increasing interest in electronics due to their (semi)conducting properties. Charge-neutral 2D c-MOFs also possess persistent organic radicals that can be viewed as spin-concentrated arrays, affording new opportunities for spintronics. However, the strong π-interaction between neighboring layers of layer-stacked annihilates active spin centers and significantly accelerates relaxation, severely limiting potential...
