“…Indeed, metal complexes are highly controversed photoinitiators/photosensitizers due to their potential toxicities and the resulting photopolymers can't be used for food packaging [290][291] or medical applications. [292][293][294][295][296][297][298][299][300][301] Recently, a great deal of efforts has been devoted to develop biosourced or bioinspired photoinitiating systems. The recent development of chalcones-based photosensitizers corresponds to this new interest, and ferrocene is also well-known to exhibit a low toxicity.…”

Photoinitiators of polymerization with reversible electrochemical properties are actively researched as these molecules can advantageously be used in photocatalytic systems, enabling to reduce the photoinitiators content within the photocurable resins. In this field, ferrocene which is extensively used by electrochemists as a reference compound for cyclic voltammetry also exhibits a significant absorption in the visible range as well as a low oxidation potential so that this metallocene was used as a potential candidate for the design of photoinitiators of polymerization. Over the years, ferrocene has been examined in numerous polymerization processes going from anionic to cationic polymerizations, but also for the freeradical polymerization of acrylates or as a sacrificial electron donor in free radical polymerization processes. Parallel to this, the development of cheap, compact and energysaving irradiation setups based on light-emitting diodes (LEDs) have clearly favored the development of visible light photoinitiators and this technology has nowadays the potential to replace the well-established UV photopolymerization. In this review, an overview of the recent development of the ferrocene-based photoinitiating systems is provided. To evidence the interest of the ferrocene derivatives recently developed, comparisons with benchmark photoinitiators will be provided.

“…Photosensitive materials used in 3D printing, in addition to their basic properties, can be modified to obtain unique parameters. The basic way to modify the resins is to change their chemical composition, which includes both the content of monomers and photoinitiating systems [75]. Modifications to the basic resin's composition affect mainly the mechanical and optical properties of the compositions; however, a much wider range of performance parameters can be reached by the preparation of composite materials [76,77].…”

The following article introduces technologies that build three dimensional (3D) objects by adding layer-upon-layer of material, also called additive manufacturing technologies. Furthermore, most important features supporting the conscious choice of 3D printing methods for applications in micro and nanomanufacturing are covered. The micromanufacturing method covers photopolymerization-based methods such as stereolithography (SLA), digital light processing (DLP), the liquid crystal display–DLP coupled method, two-photon polymerization (TPP), and inkjet-based methods. Functional photocurable materials, with magnetic, conductive, or specific optical applications in the 3D printing processes are also reviewed.

“…This initiator is known on the market as Lucirin ® TPO. The conduct of its photopolymerization follows an α-cleavage mechanism, in which TPO undergoes hemolytic α-cleavage of the carbon-phosphorus bond and generates two free radicals, ( Table 2) both capable of initiating polymerization [141][142][143][144].…”

The photoinduced polymerization of monomers is currently an essential tool in various industries. The photopolymerization process plays an increasingly important role in biomedical applications. It is especially used in the production of dental composites. It also exhibits unique properties, such as a short time of polymerization of composites (up to a few seconds), low energy consumption, and spatial resolution (polymerization only in irradiated areas). This paper describes a short overview of the history and classification of different typical monomers and photoinitiating systems such as bimolecular photoinitiator system containing camphorquinone and aromatic amine, 1-phenyl-1,2-propanedione, phosphine derivatives, germanium derivatives, hexaarylbiimidazole derivatives, silane-based derivatives and thioxanthone derivatives used in the production of dental composites with their limitations and disadvantages. Moreover, this article represents the challenges faced when using the latest inventions in the field of dental materials, with a particular focus on photoinitiating systems based on iodonium salts. The beneficial properties of dental composites cured using initiation systems based on iodonium salts have been demonstrated.
