摘要

We synthesized linear melanin-like polymers via mechanochemical Suzuki polymerization. Compared to PDA NPs

its antioxidant capacity has been significantly enhanced. Additionally

we prepared a melanin-like alternating copolymer using this method. It exhibited a fluorescence

emission wavelength that could reach up to 510 nm with a

of 8.94%.

Abstract

Polydopamine-based melanin-like materials have been widely used in the fields of ultraviolet (UV) shielding

solar desalination and anti-inflammatory treatment owing to their unique physical properties. The well-established synthesis of polydopamine nanoparticles involves the oxidative polymerization of dopamine-derived monomers

resulting in cross-linked nanostructures with high complexity and heterogeneity. Therefore

the controlled synthesis of polydopamine-based melanin-like materials with well-defined structures and predictable properties remains challenging. Herein

we propose a mechanochemical Suzuki polymerization approach for the synthesis of linear melanin-like polymers with tunable physical properties. Compared with polydopamine nanoparticles

the mechanochemical approach offers a more flexible chain-like structure

thereby enhancing its antioxidant performance. Furthermore

this approach also enables the preparation of a melanin-like alternating copolymer that exhibits green fluorescence owing to its

-conjugated structure. This study not only offers opportunities for exploring novel synthetic melanin materials

but also provides new insights into the structure-function relationships of polydopamine-based materials.
