Photochromism: Molecules and Systems Heinz Durr, Henri Bouas-Laurent
Publisher: Elsevier Science

Wheaton has won a National Science Foundation grant to acquire a cutting-edge laser system that will advance the research of three Wheaton scientists and their students. The hybrid material consists of two photochromic molecules that can be quickly switched between two states with a laser. The two stereo-isomers of such photochromic compounds represent the distinct states of a light-switchable digital molecular system (Fig. An organic thin-film transistor with the new semiconducting layer. The methodology will be described and examples of hybrid systems with active functionalities presented. Molecular electronic memory circuits. Novel photochromic material for photoswitching applications. The researchers predict that the new semiconducting thin film, with its molecules that have electrically and optically tunable states, could lead to a variety of semiconducting systems. The $255,865 grant from NSF's Major Research Instrumentation Buthelezi will use the new instrument in her investigations of host/guest interactions of photochromic molecules, which change color reversibly when exposed to light or heat.

To make the Transitions lenses respond to UV light, photochromic molecules are applied to the surface of the lens in a dye. Photochromism: Molecules and Systems. This system allows the frame to flex a bit without bending the lenses and distorting your view. [CrossRef] [details] Farrugia, L.
