Abstract
Developing sustainable, bio-based organic semiconductors from renewable aromatic feedstocks opens new possibilities for sustainable electronics. Here, the present work uses vanillin as a sustainable aromatic platform extracted from industrial lignin biomass waste, which is chemically transformed into a π-conjugated semiconductor. The resulting donor–acceptor–donor molecule, IsoInd-CO-diCzBu, combines reversible redox activity with high thermal stability. Complementary space-charge-limited current measurements and organic field-effect transistors successfully demonstrate hole transport in vertical devices and p-type field-effect operation. An indepth study combining gate-bias stress, thermal annealing, and single-crystal X-ray diffraction connects device behaviour with molecular structure. These encouraging results establish vanillin as a platform for developing a series of bio-based semiconductors whose molecular architecture can be tuned to improve charge transport.
