The efficiency of molecular switching in dithienylcyclopentenes can be influenced by the nature of substituents attached to the cyclopentene ring. Electron-withdrawing groups (EWG), like nitro or carbonyl groups, can enhance the rate of oxidative electrochemical switching, while electron-donating groups (EDG), like amino or alkyl groups, may slow it down. This effect is due to the impact of these substituents on the electron density of the cyclopentene, which can affect its redox properties and transition states.
