What is N-Hydroxynaphthalimide triflate?
Chemical properties
N-Hydroxynaphthalimide triflate is a low molecular weight compound with the appearance of white to light yellow powder to crystal, melting point is 212.1~214.2 °C, boiling point is 456.2±55.0 °C, density is 1.76±0.1 g/cm3, maximum absorption wavelength is 365(CH3CN) nm. It is sensitive to light and moisture and is normally stored under inert gas.
The Uses of N-Hydroxynaphthalimide triflate
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.
What are the applications of Application
N-Hydroxynaphthalimide triflate is a cationic photoinitiator and nonionic photoacid generator
What are the applications of Application
N-Hydroxynaphthalimide triflate is a cationic photoinitiator and nonionic photoacid generator used for polymer science, contact printing, and self-assembled monolayers (SAMs).
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.
