Biological Activity: Violamine R (Acid Violet 9) is a potent fluorophore. Violamine R shows environment and temperature-dependent photoluminescence (PL) intermittency in poly(vinyl alcohol) (PVOH) and potassium acid phthalate (KAP). Violamine R can be used to measure the temperatures spanning the glass-transition temperature (Tg) of the polymer host by the fluorescence intermittency or blinking in poly(vinyl alcohol) (PVA)[1][2].
