Dynamic materials derived from biobased furans: towards the ‘sleeping giant’ awakening

This focus article presents the author’s view on the problems in the development of biorefining strategies based on the use of 5-(hydroxymethyl)furfural (HMF), the key product derived from renewable plant biomass that was recognized as the ‘sleeping giant’ of the sustainable chemistry. The several key problems that hinder the large-scale production of HMF and its applicability in the laboratory organic synthesis and industry are discussed. This minireview is also focused on the development of the dynamic cross-linked polymers with controlled three-dimensional structure based on Diels–Alder reaction of biobased HMF-derived furans with maleimides. Realization of scalable technologies for an efficient production of such ‘smart’ analogues of the traditional petrochemical-based materials could be the basis for the realization of the competitive HMF-promoted biorefining.
