Recent advances on ferrocene-based photoinitiating systems

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 photocurable resins. In this field, ferrocene which is extensively by electrochemists a reference compound for cyclic voltammetry also exhibits significant absorption visible range well low oxidation potential so that metallocene was candidate design polymerization. Over years, has been examined numerous processes going from anionic cationic polymerizations, but free-radical acrylates or sacrificial electron donor free radical processes. Parallel this, development cheap, compact and energy-saving irradiation setups based on light-emitting diodes (LEDs) have clearly favored light technology nowadays replace well-established UV photopolymerization. review, an overview recent ferrocene-based photoinitiating systems provided. To evidence interest derivatives recently developed, comparisons benchmark will
