説明:

Dynamic soft materials incorporating open-shell molecules offer immense potential for applications that require tunable magnetic properties. However, achieving this potential necessitates balancing the long-range order, which is crucial for controlled magnetic interactions, with the inherent flexibility of soft matter. In this study, we introduce an amphiphilic d/π-conjugated nickel dithiolate radical anion that self-assembles into ordered structures, exhibiting reversible, temperature-dependent magnetic and structural transitions. These assemblies exhibit uniaxial magnetic anisotropy, which is rare in organic soft systems and has exceptional aqueous stability. This molecular design effectively balances the order, flexibility, and stability, addressing the key limitations of traditional soft materials. Our findings provide crucial insights into spin–spin interactions in organized systems and establish a versatile platform for various applications including nanomedicine and stimuli-responsive materials.
