Description and Uses
TPO can be used in the photo-crosslinking of PMMA composite, which can further be used as a gate insulator in organic thin film transistors (OTFTs). It can also be used in the formation of UV curable urethane-acrylate coatings. It may also be used in the photoinduced reaction for the formation of organophosphine compounds, which potentially find their usage as ligands with metal catalysts and reagents.
