“…[32] Purely organic semiconductors differentiate themselves from inorganic materials in terms of improved ability for design. [33] Indeed, even when taking into account only commercially available building blocks, there is an overwhelming amount of materials, with specific structures adjusted for a specific application. [34] Related to organic photoredox catalysis, in a series of works Zhang et al used covalent triazine frameworks in the synthesis of benzophosphole oxides, [35] porous poly-benzobisthiadiazole network in the dehalogenaton reaction of α-bromoacetophenones, [36] donor-acceptor COFs in coupling of heteroarenes with diethyl bromomalonate, [37] and poly(benzothiadiazole) in [2 + 2] cycloaddition of styrene.…”

Carbon nitrides encompass a class of transition-metal-free materials possessing numerous advantages such as low cost (few Euros per gram), high chemical stability, broad tunability of redox potentials and optical bandgap, recyclability, and a high absorption coefficient (> 10 5 cm À 1), which make them highly attractive for application in photoredox catalysis. In this Review, we classify carbon nitrides based on their unique properties, structure, and redox potentials. We summarize recently emerging concepts in heterogeneous carbon nitride photocatalysis, with an emphasis on the synthesis of organic compounds: 1) Illumination-Driven Electron Accumulation in Semiconductors and Exploitation (IDEASE); 2) singlet-triplet intersystem crossing in carbon nitride excited states and related energy transfer; 3) architectures of flow photoreactors; and 4) dual metal/carbon nitride photocatalysis. The objective of this Review is to provide a detailed overview regarding innovative research in carbon nitride photocatalysis focusing on these topics.

“…These polymers possess extended delocalized π-conjugated systems, porous structures, tunable specific surface area, broad visible light absorption ability and excellent physicochemical stability, which are tailor-made for photocatalytic applications. [10] Different from the above mentioned conjugated materials with 2D/3D structures, linear conjugated polymers with one-dimensional conjugated backbones are also promising photocatalysts due to their well-defined chemical structures and certain solubility in solvents, [11] both of which make it easier to explore the correlation between the chemical structures and photocatalytic activity. [12] The large realm of conjugated building blocks endows conjugated materials-based photocatalysts with a broad range of characteristics and functions, providing a good platform to design highly efficient photocatalysts.…”

Photocatalytic hydrogen evolution is viewed as a promising green strategy to utilize the inexhaustible solar energy and provide clean hydrogen fuels with zeroemission characteristic. The nature of semiconductor-based photocatalysts is the key point to achieve efficient photocatalytic hydrogen evolution. Conjugated materials have been recently emerging as a novel class of photocatalysts for hydrogen evolution and photocatalytic reactions due to their electronic properties can be well controlled via tailormade chemical structures. Hydrophilic conjugated materials, a subgroup of conjugated materials, possess multiple advantages for photocatalytic applications, thus spurring remarkable progress on both material realm and photocatalytic applications. This minireview aims to provide a brief review of the recent developments of hydrophilic conjugated polymers/small molecules for photocatalytic applications, and special concern on the rational molecular design and their impact on photocatalytic performance will be reviewed. Perspectives on the hydrophilic conjugated materials and challenges to their applications in the photocatalytic field are also presented.

In the past decades, enormous efforts have been put into visible light–promoted photocatalytic chemical transformations. Among the intensely studied photocatalytic systems, metal‐free, pure organic and heterogeneous photocatalysts based on conjugated microporous polymers (CMPs), a class of organic porous materials featuring π‐conjugated backbone and permanent microporosity, draw much attention. The CMP‐based photocatalysts are highly attractive because of their pure organic nature, ease of synthesis, structural diversity, and nontoxicity, as well as low costs. Over the past years, various CMPs have been synthesized for a broad range of photocatalytic applications. Herein, the aim is to deliver an updated summary of this field with the focus on crucial factors, which largely affect the catalytic performance of CMPs. To name a few, band structure, charge separation and transfer, and morphology are described combined with specific energy‐ and organosynthesis‐related applications such as water splitting, CO2 reduction, organic photoredox reactions, etc.
