“…The first-principles calculations showed that the effective electron–hole separation was achieved in TAPB-TTB COF due to strong donor–acceptor interaction compared to TTA-TTB COF. In line with this result, another report appeared in the literature, wherein two crystalline, 2D COFs were realized by Schiff base condensation of 1,3,5-tris(4-formylbiphenyl)benzene (TFBB) and 2,4,6-tris(4-aminophenyl)-1,3,5-triazine (TAT) to yield TFBB–TAT, representing a D–A network . On the other hand, polycondensation of TFBB and 2,4,6-tris(4-aminophenyl)benzene (TAB) resulted in TFBB–TAB COF, representing a D-D type framework structure.…”

Hydrogen (H2), the next-generation green fuel, can be obtained by the catalytic splitting of water using solar and electrochemical methods and a combination of both (photoelectrochemical). Among the various porous catalytic water reduction systems developed, covalent organic frameworks (COFs) based systems are emerging in recent times due to their structural ordering and facile tunability, high thermo-chemical stability, and permanent porosity. This review provides a detailed summary and analysis of COF-based photo-, electro-, and photoelectrochemical hydrogen evolution systems. Uniquely, it includes the journey from precious noble metal to earth-abundant molecular cocatalysts for the generation of H2 and their synergetic interaction with COFs. Moreover, the focus is on outlining the core concept of heterogeneous catalytic H2 evolution, measurement techniques, photophysical and physicochemical insights, and the relationship among key components of the overall process. Finally, the advantages and pitfalls of COFs as H2 evolution systems and the design principles for optimal catalytic efficiency are discussed. A dedicated outlook section is presented at the end to benefit researchers for future developments in this emerging field.

“…We further emphasize that many of these questions have applications that transcend the photoelectrochemistry of solar fuels and if resolved, have fundamental implications across a number of energy conversion and storage platforms. We focus here on PEC water splitting by soft photoelectrodes, but the questions raised are equally relevant to soft polymer PEC carbon dioxide reduction, which is a rapidly expanding field in its own right. − While some issues highlighted here are also relevant to the emerging field of covalent organic frameworks (COFs) for PEC applications, we focus here on π-conjugated semiconducting polymers, and refer readers to related work focused on COFs. − …”

Polymer semiconductors are fascinating materials that could enable delivery of chemical fuels from water and sunlight, offering several potential advantages over their inorganic counterparts. These include extensive synthetic tunability of optoelectronic and redox properties and unique opportunities to tailor catalytic sites via chemical control over the nanoenvironment. Added to this is proven functionality of polymer semiconductors in solar cells, low-cost processability, and potential for large-area scalability. Herein we discuss recent progress on soft photoelectrochemical systems and define three critical knowledge gaps that must be closed for these materials to reach their full potential. We must (1) understand the influence of electrolyte penetration on photoinduced charge separation, transport, and recombination, (2) learn to exploit the swollen polymer/electrolyte interphase to drive selective fuel formation, and (3) establish co-design criteria for soft materials that sustain function in the face of harsh chemical challenges. Achieving these formidable goals would enable tailorable systems for driving photoelectrochemical fuel production at scale.
