Abstract The development of new procedures aiming at reducing the environmental impact of polymerization processes is a major societal issue. In this field, light-assisted polymerization and especially visible light photopolymerization can address this issue by enabling in the future, Sun, to be used as the irradiation source. Presently, numerous visible light photoinitiators (xanthene dyes, porphyrins and phthalocyanines) are used in industry but their toxicities constitute a major issue for future uses of polymers. Therefore, photopolymerization is facing a short-term challenge and the development of visible light photoinitiators of polymerization has become a blooming field of research during the last decade. An ever-growing effort is thus done to develop new structures, effort which is also supported by the recent applications of photopolymerization in 3D-printing. Depending on the applications, use of synthetic photoinitiators can constitute a severe limitation for future applications of photopolymers so that the use of natural products has been identified as a promising alternative to address the toxicity or the biocompatibility issues. In this review, an overview of the different visible-light photoinitiators based on natural products is provided.

减少环境影响的聚合光引发剂：大自然作为染料的无限可再生来源

摘要 旨在减少聚合过程对环境的影响的新程序的开发是一个主要的社会问题。在该领域，光辅助聚合，尤其是可见光光聚合可以解决这个问题，未来可以将 Sun 用作辐射源。目前，工业中使用了许多可见光光引发剂（呫吨染料、卟啉和酞菁），但它们的毒性构成了聚合物未来用途的主要问题。因此，光聚合正面临短期挑战，近十年来，可见光聚合引发剂的开发已成为一个蓬勃发展的研究领域。因此，人们不断努力开发新的结构，最近光聚合在 3D 打印中的应用也支持了这一努力。根据应用，合成光引发剂的使用可能对光聚合物的未来应用构成严重限制，因此使用天然产品已被确定为解决毒性或生物相容性问题的有前途的替代品。在这篇综述中，概述了基于天然产物的不同可见光光引发剂。
