Electrochemical tuning and structural modification of thiophene‐substituted siloles led to silole chromophores with efficient and stable electrochemiluminescence (ECL). By extending silole π conjugation with thiophene units and by constraining the applied potential range, stable radical cations favorable for ECL emission were generated (see graph for an example).
