    Abstract Graphitic carbon nitride (g-C₃N₄) has emerged as a new research hotspot, attracting broad interdisciplinary attention in the form of metal-free and visible-light-responsive photocatalysts in the field of solar energy conversion and environmental remediation. These photocatalysts have evolved as attractive candidates due to their non-toxicity, chemical stability, efficient light absorption capacity in the visible and near-infrared regions, and adaptability as a platform for the fabrication of hybrid materials. This review mainly describes the latest advances in g-C₃N₄ photocatalysts for chemical transformations. In addition, the typical applications of g-C₃N₄-based photocatalysts involving organic transformation reactions are discussed (synthesis of heterocycles, hydrosulfonylation, hydration, oxygenation, arylation, coupling reactions, etc.).

    Abstract The field of photoredox catalysis has been transformed by the use of organic photocatalysts, which give access to re-activities that were previously only possible with transition-metal photocatalysts. Recent advancements in the use of an acridinium photocatalyst in organic synthesis are covered in this review. Both the late-stage functionalization of biorelevant molecules and the activation of inert chemical bonds are explored, with an emphasis on their mechanistic features.

    Abstract Photocatalysis has proven to be an effective approach for the production of reactive intermediates under moderate reaction conditions. The possibility for the green synthesis of high-value compounds using the synergy of photocatalysis and biocatalysis, benefiting from the selectivity of enzymes and the reactivity of photocatalysts, has drawn growing interest. Mechanistic investigations, substrate analyses, and photobiocatalytic chemical transformations will all be incorporated in this review. We seek to shed light on upcoming synthetic opportunities in the field by precisely describing mechanistically unique techniques in photobiocatalytic chemistry.

    Abstract 1,3-Dicyano-2,4,5,6-tetrakis(diphenylamino)-benzene (4DPAIPN), with diphenylamino as an electron donor and dicyanobenzene as an electron acceptor, is a typical donor-acceptor fluorophore. Due to its excellent redox window, good chemical stability and broad applicability, this fluorophore has emerged as a powerful and attractive metal-free organophotocatalyst. This review has highlighted the design, synthesis and application of 4DPAIPN photoredox catalysts as well as their exceptionally broad range of redox properties. This flourishing class of organophotocatalysts is expected to contribute to a great extent toward the advancement of synthetic methodologies and its adaptation to a large scale inventive implementation due to their flexibility.
