Photochromism

Photochromism is a chemical process in which a compound undergoes a reversible change between two states having separate absorption spectra, i.e. different colours, whether the compound is in a crystalline, amorphous or solution state. Applications now go beyond the well-known ophthalmic, fashion and novelty applications into data storage, photoswitching, optical computing, sensing and others in the biomedical area. The development of functional, wearable garments has been of increasing interest, utilising photochromic, thermochromic and especially flexible electrochromic materials.
