General description

Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (TPO) is a monoacylphosphine oxide based photoinitiator that can be incorporated in a variety of polymeric matrixes for efficient curing and color stability of the resin.

application

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.
