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-Fe_2O_3 nanoparticles through self-assembly,coordination and calcination,which displayed excellent electrochemical performance as anode materials for Li-ion batteries.
