Resumen en inglés

Divanillin was synthesized in high yield and purity using Laccase from Trametes versicolor. It was then pol-ymerized with Benzene-1,4-diamine and 2,7-diaminocarbazole to form polyazomethines. Polymerizations were performed under microwave irradiation and without transition-metal based catalyst. These bio-based conjugated polyazomethines present a broad fluorescence spectrum ranging from 400 to 600 nm. Depending on the co-monomer used, polyazomethines with molar masses around 10 kg.mol-1 and with electronic gaps ranging from 2.66 to 2.85 eV were obtained. Furthermore, TD-DFT calculations were performed to corroborate experimental results.< Leer menos
