Abstract:
An apparatus and method provide a solute-solvent solution that allows the solute to become photo-protonated by the solvent on absorption of ultraviolet light. The solute is 1,2,3,4,5,6,7,8-octamethylanthracene (OMA). The solvent is 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP). The protonated form of the solute absorbs visible light to change the coloration of the solution from a substantially clear state to a colored state.
