Forest biomass is viewed as a significant source of organic carbon and thus the ideal replacement of petroleum products. From the resources derived from biomass, lignocellulose is the most abundant biobased material on earth. One of the aromatic added value compounds obtained from the depolymerization of lignin is vanillin. Here, we report the preparation of new compounds having benzothiophene, indole, isatin, benzofuroxan, benzofurazan, benzothiadiazole, and phthalimide heteroaromatic ring structures. More precisely, our results show that vanillin can be used as a biosourced starting material for the preparation of a variety of aromatic dibrominated monomers. X-ray crystallography on single crystals was also performed to obtain meaningful information on their solid-state ordering. This work opens the way to new, sustainable, biosourced aromatic materials (small molecules or polymers) for organic electronics.

用于有机电子材料的生物来源香草醛基构建块

森林生物质被视为有机碳的重要来源，因此是石油产品的理想替代品。从生物质来源的资源来看，木质纤维素是地球上最丰富的生物基材料。从木质素解聚获得的芳香族附加值化合物之一是香草醛。在这里，我们报告了具有苯并噻吩、吲哚、靛红、苯并呋喃、苯并呋喃、苯并噻二唑和邻苯二甲酰亚胺杂芳环结构的新化合物的制备。更准确地说，我们的研究结果表明，香草醛可用作制备各种芳香族二溴化单体的生物原料。还对单晶进行了 X 射线晶体学，以获得有关其固态排序的有意义的信息。这项工作开辟了通往新的、可持续的、
