General description

3-(Triphenylphosphonio)propane-1-sulfonate is a zwitterionic, sulfonic acid-functionalized ionic liquid.

Application

3-(Triphenylphosphonio)propane-1-sulfonate has been used as a zwitterion to study its effect on the work function of indium tin oxide (ITO) in inverted polymer solar cells (PSCs). It can be used in the preparation of triphenyl-(3-sulfopropyl)phosphonium phosphotungstate, an efficient green catalyst for esterification reactions.
