The Front Cover encapsulates our narrative: an aspen tree is a lignin source, while structural details appear on the blackboard. Visual elements illustrate the lignin extraction process: wood chips, extraction setup, and resulting powder. A figure holds the culmination of research—a cartridge, symbolizing the chemical evolution of lignin. The filled cartridge is placed on a table and ready for deployment. More information can be found in the Research Article by Y. Karpichev and co-workers. Cover art by Mahendra K. Mohan.

封面：木质素的氯甲基化作为交叉偶联和点击反应中具有催化性能的功能材料的途径 (ChemSusChem 8/2024)

封面概括了我们的叙述：白杨树是木质素的来源，而结构细节则出现在黑板上。视觉元素展示了木质素提取过程：木片、提取装置和所得粉末。一个人物拿着研究的顶峰——一个墨盒，象征着木质素的化学演化。填充的墨盒被放置在桌子上并准备好部署。更多信息可以在 Y. Karpichev 及其同事的研究文章中找到。封面艺术由 Mahendra K. Mohan 绘制。
