photochromism การใช้

• :Check out our article on photochromism.
• The photochromism is due to electrocyclic cleavage of the C-spiro-O bond with photoexcitation.
• Both processes are often applied in molecular switches and for photochromism ( reversible state changes from exposure to light ).
• Another requirement of photochromism is two states of the molecule should be thermally stable under ambient conditions for a reasonable time.
• Another potential explanation is photochromism, where changes in lighting level affect the actual ( not just apparent ) light absorption profile of an object.
• Dr . Staebler has performed research investigations on photochromism in materials, electrochromism, storage of holograms in electro-optic crystals, plus amorphous silicon solar cells produced by discharge.
• A number of sunglass manufacturers and suppliers including Tifosi, Intercast, Serengeti Eyewear, and Persol provide tinted lenses that use photochromism to go from a dark to a darker state.
• Although many approaches to molecular identification exist, the light-induced photochromism of selected fluorophores developed as the most promising approach to distinguish neighboring molecules by separating their fluorescent emission in time.
• When the spiropyran is in a solution with polar solvents or when it receives heating ( thermochromism ) or radiation ( photochromism ) it becomes coloured because its structure has changed and it has been transformed into the merocyanine form.
