Cycle contraction and symmetrisation in redox-active ligands: from alloxazine to isoimidazolonequinoxaline derivatives and their electrochemical and coordination studies

Key Points

• Electrochemical properties reveal significant characteristics of redox-active ligands L1 and L2.
• Both ligands exhibit notable abilities to form pillared metal-organic frameworks (MOFs).
• Analysis focuses on ligands derived from 1,4-bis(pyrid-3-yl)benzene, highlighting their versatility.
• These findings suggest promising applications in material science, especially for responsive systems.
