“…Benzylidene ketone is a versatile scaffold for the design of photobleachable photoinitiators. [189,[232][233][234][235][236][237] Indeed, if excellent photoinitiating abilities were obtained by introducing peripheral triphenylamine or carbazole groups in C61 and C62, introduction of phenothiazine was examined by Qu and coworkers. [238] Indeed, phenothiazine is a wellknown electron donor that was used for the design of numerous photoinitiators due to the easiness of chemical modifications.…”

“…Monomers can be transformed into polymers under irradiation (e.g., UV and visible light) in photopolymerization. Photopolymerization demonstrates numerous advantages, such as no VOCs, excellent controllability, and high efficiency [ 1 , 2 , 3 , 4 , 5 ]. Currently, photopolymerization is applied in many fields, including coatings [ 6 , 7 , 8 ], adhesives [ 9 , 10 , 11 ], 3D printing [ 12 , 13 , 14 , 15 ], biomaterials [ 16 , 17 , 18 ], the microelectronics industry [ 19 , 20 , 21 ], etc.…”

High-Performance Photoinitiating Systems for LED-Induced Photopolymerization

Currently, increasing attention has been focused on light-emitting diodes (LEDs)-induced photopolymerization. The common LEDs (e.g., LED at 365 nm and LED at 405 nm) possess narrow emission bands. Due to their light absorption properties, most commercial photoinitiators are sensitive to UV light and cannot be optimally activated under visible LED irradiation. Although many photoinitiators have been designed for LED-induced free radical polymerization and cationic polymerization, there is still the issue of the mating between photoinitiators and LEDs. Therefore, the development of novel photoinitiators, which could be applied under LED irradiation, is significant. Many photoinitiating systems have been reported in the past decade. In this review, some recently developed photoinitiators used in LED-induced photopolymerization, mainly in the past 5 years, are summarized and categorized as Type Ⅰ photoinitiators, Type Ⅱ photoinitiators, and dye-based photoinitiating systems. In addition, their light absorption properties and photoinitiation efficiencies are discussed.

“…Chalcones are type of natural dye that also exist in many plants, and chalcone-based photoinitiators are easily accessible and have good light absorption performance in the near-ultraviolet-visible region. Chalcones also have an ideal structure for designing visible light photoinitiators to induce photopolymerization reactions, 22 while chalcone-based photoinitiators have good photobleaching properties and good biocompatibility, making them suitable for a wide range of applications in 3D printing and dental materials. 23 Triphenylamine (TPA) is one of the most widely used electron donors in the fields of organic light-emitting materials and light-induced color-changing materials.…”
