Photochromism.Molecules.and.Systems.pdf. Photochromism is simply defined as the light induced reversible change of colour. Molecular systems with integrated chemical reactivity and photochromic functions are potentially beneficial for the development of novel functional materials. New York: Oxford University Press. A molecule will typically absorb one . 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. Photochromism: Molecules and Systems. Two are pale yellow crystals that are not fluorescent at room temperature and exhibit photochromism (molecule 1 and 4), while the other two (molecule 2 and 3) are not photochromic , but exhibit fluorescence in the solid state.

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). It is important for students to understand that chemical reactions can take place without the addition of other chemicals or elements to the system, which in directly observable in this isomerization. Abstract: Photochromic diarylethenes (DAEs) are among the most promising molecular switching systems for future molecular electronics.
