Biobased organogels


Organogels are used in a wide range of applications for which the development of new bio-based organogelators is highly desirable. While furan-2,5-dicarboxylic acid (FDCA) is a promising molecule for the synthesis of bio-based polyesters, it has never been used in the context of organogels. This study explores the possibility to design FDCA-based organogelators that self-assemble into fibrillar networks stabilized by hydrogen bonding. Gelation tests show the versatility of this gelator family with a wide variety of gelled liquids, especially apolar liquids. The structure of the gels was investigated by FTIR and CD spectroscopies, cristallography, powder X-ray diffraction and rheology.

  • FDCA-based, low-molecular weight organogelators (LMWOG) were synthesized succesfully
  • LMOGs are made from 100% bio-based molecules
  • Crystallography demonstrated its π-π stacked assembly
  • Rheology proved their viscoelastic behaviour, with gel-formation from 1% by weight
  • Self-assembly occurs from 1mM and remains arranged at high temperatures
  • Technology has been patented in collaboration with SATT Lutech
