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

A molecule will typically absorb one . Molecular electronic memory circuits. The two stereo-isomers of such photochromic compounds represent the distinct states of a light-switchable digital molecular system (Fig. Molecules and Systems, edited ); Bach et al. EPJ B - Condensed Matter and Complex Systems. Recent results on nanoparticles modified with light sensitive molecules have demonstrated reverse photochromism. The research group had already reported a super highly sensitive photochromic molecule with a 100% coloring sensitivity. Many windshields block UV light, thus the UV light can't interact with the photochromic molecules, and the wearer could experience no sunglasses effect when driving. (1980 [Florin, I., Rutburge, L., Curvall, M. In Thiazoles and their Benzo Derivatives, edited ); Florin et al. The methodology will be described and examples of hybrid systems with active functionalities presented. As the pi-system extends further and further, the wavelength of light absorbed becomes longer and longer, until extended pi-systems begin to absorb light in the visible spectrum – and the molecule becomes colored (see figure). Fast andreversible photoinduced structural changes characteristic of photochromic materials are particularly interesting as they imply the use of molecular systems for all-optical switching.
