General description

Diphenyliodonium nitrate (DPIN) is a photoacid generator (PAG) that goes through photolysis reaction which can be used in the lithographic formation of UV reactive polymers. It can also be used in forming a light tuned self-assembled polyelectrolytic structures.[1][2]

Application

Cationic photoinitiator. Photoacid generator.
DIPN can be used in the photo patterning of UV tuned shape memory hydrogels which can potentially be used in 3D printing.[1][2][3]
