Radical-to-radical push–pull effect enhances single-molecule conductance in asymmetric diradicals

Key Points

• The study aims to explore how asymmetry influences the electron spin effect in diradicals and their conductance properties.
• Examined the structural design of asymmetric diradicals.
• Analyzed the modulation of diradical character due to the push-pull effect.
• Measured single-molecule conductance under varying conditions.
• The asymmetrical configuration significantly enhances the conductance.
• The push-pull electron spin effect was confirmed to influence the diradical character.
• Observations suggest that modifying asymmetry can lead to better electronic properties.
