Triphenylsulfonium trifluoromethanesulfonate Chemical Properties, Uses, Production

Uses

TPS-tfs can be used as photoacid generators for the preparation of a bilayer system based nanoporous template which can be potentially used in sensor applications. It can also be used to form a blend with polyfluorene-co-benzothiadiazole for the fabrication of organic light emitting diodes (OLEDs).

General Description

Triphenylsulfonium triflate (TPS-tf) is a photo-acid generator which can be incorporated in conjugated polymers to enhance the luminescence and reduce the operating voltage. The performance efficiency of the fabricated device is increased by improving the mobility of charge carriers.
