In recent years, significant attention has focused on adsorber materials based on lignin. However, only 5% of the available lignin is exploited worldwide, thus significant opportunities for materials development still exist. Lignin has been vastly utilized as a feedstock for the synthesis of adsorbers for the removal of dyes and toxic organic molecules . To improve adsorption capacity, lignin can be chemically modified with oxygen-, nitrogen-, or sulfur-containing functional groups. Most frequently the phenolic groups of lignin were modified. In order to extend the application of lignin as adsorbers, we are especially interested in the chemical modification of this natural resource with a bio-based linear difluoro oligomers LOx (di- or monofunctional) or a heterocyclic monomer (Figure).
