Key Points

The aim is to explore how increasing s-orbital character and using rigid ligands affect electron spin interactions.
Experimental design focused on electron spin systems within a carbon ring framework.
Use of rigid ligands to introduce zero nuclear spin and suppress coupling effects.
Successful suppression of spin-orbit coupling and hyperfine coupling in the s-orbital character increase.
