General description
N-Hydroxynaphthalimide triflate (HNT) is a photoacid generator(PAG) that forms an acid upon exposure to UV light which can be used to generate patterned structures. It can also be used to tune the solubility of a polymer by forming acid linkages.
Application
HNT can be used to form patterned nanoparticles that find potential applications in volumetric manufacturing of semiconductor devices. It can also be used in the photo-responsive pore reopening of zeolites that facilitates the regulation of the gas permeation process. UV-irradiated trimethylsilyl ultrathin cellulose based films can be formed in presence of HNT as a PAG.
