The three-year grant also Their work will use a sophisticated instrument, the nanosecond pulsed laser/detection system, which the college acquired through a previous NSF grant that she and her colleagues received in 2011. To make the Transitions lenses respond to UV light, photochromic molecules are applied to the surface of the lens in a dye. Photochromic molecules can be loosely divided into two types: those that returnto their initial state at a rate dependent on the ambient temperature ("thermally reversible" photochromic materials), and those which are thermally stable, . The research award from the National Science Foundation (NSF) will focus on deepening scientists' understanding of spiropyrans, a type of photochromic molecules that change color when exposed to light and heat. Fast andreversible photoinduced structural changes characteristic of photochromic materials are particularly interesting as they imply the use of molecular systems for all-optical switching. The research group had already reported a super highly sensitive photochromic molecule with a 100% coloring sensitivity.

UV light excitation occurs Absorption Spectra of Spirooxazine Photochromic System. JFS accepts donations from around the world, by Justgiving, a secure web payment system. Among the most important categories of photochromic molecules there are spirocompounds which can induce excellent colouration during irradiation [7–9]. One-Color Reversible Control of Photochromic Reactions in a Diarylethene Derivative: Three-photon Cyclization and Two-Photon Cycloreversion by Near IR Femtosecond Laser Pulse at 1.28 μm. Photochromism is simply defined as the light induced reversible change of colour.
