Molecular Design, Synthetic Strategies, and Applications of Cationic Polythiophenes

This review delves into the synthesis of cationic-functionalized oligothiophenes and polythiophenes, their properties, and their diverse applications from the year 2002 to 2019. Pristine polythiophene chains are hydrophobic and are not easily converted into a form that is useful for broad applicatio...
