Lignin2Day – Lignin Chemistry and Multi-Dimensional Analysis
The group “Lignin2Day” is working towards a more comprehensive understanding of lignin structure and composition by developing novel analytical methods using multidimensional approaches. The aim is to elaborate the intricate interrelationships between the main chemical features of lignin, including molar mass, functionality, monomeric composition, bonding pattern and molecular architecture, its properties and chemical behavior in diverse applications. A key technique to achieve this in-depth characterization of lignin is separation by liquid chromatography (LC) in size-exclusion or interaction mode, and the combination thereof, i.e., two-dimensional LC approaches. In addition, hyphenation with NMR or FTIR allows structural elucidation and chemical profiling of lignins. We thereby aim to provide essential information to study reaction mechanisms and structure-property relationships.
New analytical methods are also needed for the exponentially growing number of lignin derivatives and materials that are currently explored and developed. Hence, we are also concerned with the adaptation and further development of existing procedures to meet the demands of fast, facile, yet reliable analytics for use in academia and industry alike. We work on solutions for lignin and its derivatives, lignin-containing materials (e.g., pulping liquors, lignin-carbohydrate complexes, lignin-co-polymers, lignin nanoparticles, lignin-based binders and adhesives, etc.), and other polyphenolic compounds (i.e., tannins) and their derivatives.
