In this context, light-driven chemical reactions are the most favorable techniques due to the milder reaction conditions and lower energy requirements . Additionally, light-mediated polymerization reactions can establish spatial and temporal control which is crucial for electronic devices . Although, there have been few works reporting the photooxidative polymerization of EDOT using photoinitiating systems having graphitic carbonitride (g-CN) or titanium dioxide (TiO2) , none of these works reported the synthesis of high molecular weight pristine PEDOT (not hybrid composite) using a single-component photoinitiating system.
