Synthesis, Self-assembly and Electrode Application of Mussel-inspired Alternating Copolymers

We reported the first mussel-inspired alternating copolymer with a high amount of catechol groups (50% molar ratio) through a facile epoxy-amino click reaction between 9,9-bis(4-(2-glycidyloxyethyl)phenyl fluorene (BGEPF) and dopamine (DA). The obtained copolymers were used to prepare carbon/nitrogen-doped α-Fe2O3 nanoparticles through self-assembly, coordination and calcination, which displayed excellent electrochemical performance as anode materials for Li-ion batteries.
