“…introduced a thiophene‐containing covalent triazine framework (CTF) located on mesoporous silica (SBS‐15) as a PC for the efficient and selective oxidation of alcohols to aldehydes and ketones with molecular oxygen as a green oxidant [Eq. (29)] . It is suggested that the uniform formation of CTF‐Th 99 inside the mesopores of SBA‐15 is due to the even distribution of carbon, nitrogen, and sulfur atoms in the material, which was confirmed by using elemental mapping.…”

Sulfur-containing compounds (SCCs) exist widely in, for example, natural sources, pharmaceuticals, materials, and foods. Their multifarious functions have stimulated scientists to construct them in greener and more efficient ways and further exploit their properties. Different photosensitizers with sulfur atoms have been developed and exploited. Furthermore, SCCs display excellent ability in hydrogen-atom-transfer reactions. In addition to acting as catalysts, SCCs can also be efficiently transformed under visible-light-promoted conditions. Bond dissociation and oxygenation reactions that involve sulfur centers are emphasized here.

“…In particular, the semiconductor redox potentials of CPs can be precisely modified through electron‐donor or electron‐acceptor combinations, which in principle also create organic dyadic structure to facilitate charge separation. Recent research has demonstrated the use of CMPs in a variety of organic photoredox reactions . Cooper et al.…”

The reduction of CO2 with visible light is a highly sustainable method for producing valuable chemicals. The function‐led design of organic conjugated semiconductors with more chemical variety than that of inorganic semiconductors has emerged as a method for achieving carbon photofixation chemistry. Here, we report the molecular engineering of triazine‐based conjugated microporous polymers to capture, activate and reduce CO2 to CO with visible light. The optical band gap of the CMPs is engineered by varying the organic electron‐withdrawing (benzothiadiazole) and electron‐donating units (thiophene) on the skeleton of the triazine rings while creating organic donor–acceptor junctions to promote the charge separation. This engineering also provides control of the texture, surface functionality and redox potentials of CMPs for achieving the light‐induced conversion of CO2 to CO ambient conditions.

Oxidation reactions are a key technology to transform hydrocarbons from petroleum feedstock into chemicals of a higher oxidation state, allowing further chemical transformations. These bulk scale oxidation processes usually employ molecular oxygen as the terminal oxidant as at this scale it is typically the only economically viable oxidant. The produced commodity chemicals possess limited functionality and usually show a high degree of symmetry thereby avoiding selectivity issues. In sharp contrast in the production of fine chemicals preference is still given to classical oxidants. Considering the strive for greener production processes the use of O2, the most abundant and greenest oxidant, is a logical choice. Given the rich functionality and complexity of fine chemicals achieving regio/chemoselectivity is a major challenge. This review presents an overview of the most important catalytic systems recently described for aerobic oxidation, and the current insight in their reaction mechanism.
