摘要

木质素是最丰富的芳香族生物聚合物,正在成为即将到来的可持续材料加工革命的中流砥柱。尽管木质素的异质结构带来了固有的挑战,但近来在开发创新战略方面取得了重大进展,这些战略旨在通过光反应来利用这种迷人的芳香族生物聚合物,从而提供行业所需的产品。本综述旨在深入探讨木质素辅助光反应的创新方法,重点关注通过光聚合作用构建功能性聚合物材料和通过光还原作用提供有价值的化学品,其中木质素可分别用作大分子光引发剂和还原性光催化剂。此外,还总结了提高木质素在光聚合反应中的光化学量子产率以及利用木质素大分子作为光致聚合物促进光催化反应中电子转移的现有策略。未来,这种光化学木质素价值化概念有可能为实现综合生物精炼工艺的盈利价值链提供新的可能性。

Lignin-Assisted Photoreactions: Unveiling New Frontiers in Light-Induced Chemistry.

Lignin, the most abundant aromatic biopolymer, is emerging as a mainstay of the upcoming revolution in sustainable materials processing. Despite the inherent challenges associated with the heterogeneous structure of lignin, significant progress has recently been made in developing innovative strategies to valorize this fascinating aromatic biopolymer to deliver industry-demanded products via photoreactions. The purpose of this concept article is to unravel insights into these creative approaches in lignin-assisted photoreactions, focusing on photopolymerization to construct functional polymeric materials and photoreduction to provide valuable chemicals, wherein lignin serves as a macromolecular photoinitiator and a reductive photocatalyst, respectively. The existing strategies for improving the photochemical quantum yield of lignin in photopolymerization and harnessing lignin macromolecules as photoresponsive polymers to facilitate electron transfer in photocatalytic reactions are also summarized. In the future, such photochemical lignin valorization concepts could potentially provide new possibilities for achieving a profitable value chain for integrated biorefinery processes.
