“…Indeed, photopolymerization is used in a wide range of applications of photopolymerization from coatings and varnishes, adhesives, solvent-free paints and dental restoration materials to 3D/4D printing and microelectronics [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. If the reactivity of photoinitiators remains the main parameter governing the design of new structures, their toxicities and biocompatibilities are more and more regarded [16][17][18][19]. Indeed, for applications such as food packaging and different bioapplications, the toxicity of the final polymers and more generally the final composites (obtained by the introduction of fillers in polymers) is of crucial importance.…”

The design of biosourced and/or bioinspired photoinitiators is an active research field as it offers a unique opportunity to develop photoinitiating systems exhibiting better biocompatibility as well as reduced toxicity. In this field, flavonoids can be found in numerous fruits and vegetables so these structures can be of interest for developing, in the future, polymerization processes, offering a reduced environmental impact but also better biocompatibility of the polymers. In this review, the different flavonoids reported to date as photoinitiators of polymerization are presented. Over the years, different modifications of the flavonoid scaffold have been examined including the grafting of well-known chromophores, the preparation of Type II photoinitiators or the introduction of photocleavable groups enabling the generation of Type I photoinitiators. Different families of flavonoids have also been investigated, enabling to design of high-performance photoinitiating systems.
