What is 2-[3-(2H-Benzotriazol-2-yl)-4-hydroxyphenyl]ethyl methacrylate?
The Uses of 2-[3-(2H-Benzotriazol-2-yl)-4-hydroxyphenyl]ethyl methacrylate
It finds use
- in intraocular lenses,
- as a UV absorber (UVAs)?
General Description
It is capable of absorbing ultraviolet radiation (UV) and dissipate the energy in the form of heat, in sub-picosecond time scale. For the benzotriazole class of UV absorbers, the mechanism of excited-state deactivation is due to an excited-state intramolecular proton transfer.
