“…Afterward, this radical adds to the acyl radical, resulting in the covalent modification of the TMD (Figure 7). [35] Energy-wise, the energy levels of the valence and conduction band of 2H-MoS 2 are −5.7 and −3.85 eV, respectively, [4b] while 2H-MoSe 2 lie at −5.05 and −3.50 eV, respectively. [17] This is further supported by the DPV assays (cf.…”

Transition metal dichalcogenides (TMDs) are promising 2D nanomaterials for diverse applications, but their intrinsic chemical inertness hinders their modification. Herein, a novel approach is presented for the photocatalytic acylation of 2H‐MoS2 and 2H‐MoSe2, utilizing tetrabutyl ammonium decatungstate ((nBu4N)4W10O32) polyoxometalate complex as a catalyst and a conventional halogen lamp as a source of irradiation. By harnessing the semiconducting properties of TMDs, new avenues emerge for the functionalization of these materials. This novel photocatalytic protocol constitutes the first report on the chemical modification of 2D nanomaterials based on a catalytic protocol and applies to both aliphatic and aromatic substrates. The scope of the decatungstate‐photocatalyzed acylation reaction of TMDs is explored by employing an alkyl and an aromatic aldehyde and the success of the methodology is confirmed by diverse spectroscopic, thermal, microscopy imaging, and redox techniques. This catalytic approach on modifying 2D nanomaterials introduces the principles of atom economy in a functionalization protocol for TMDs. It marks a transformative shift toward more sustainable and efficient methodologies in the realm of TMD modification and nanomaterial chemistry.

“…The molecule in the T 1 state can generate free radicals or singlet oxygen for the photodynamic effect through type I and type II effect [40] . In continuation of our work on photocatalysed organic synthesis [41–65] in this review article, the recent applications of visible light induced photocatalytic trends for the functionalization of anticancer organic compounds via different modes are reviewed. This review might be particularly useful for those who are already involved in the area of medicinal organic synthesis to carry out visible light mediated photocatalysed reactions.…”

Visible light photocatalysis has several applications as a method of chemical transformation, with wide‐ranging effects on the production of energy, preservation of the environment, the development of new drugs and human health. The light‐induced sensitization of cofactors for photodynamic therapy in the treatment of cancer is a remarkable application with an influence on human health. The use of this photosensitization strategy in medicine has sparked interest in other photochemical techniques, such as photoredox catalysis, that could have an impact on biological research. The discovery of useful synthetic chemical transformations during the past ten years has made light‐mediated catalysis a highly used method for chemical synthesis. This review will highlight the recent advances of visible‐light photocatalysis through its application in anticancer activity.
