2,2,6,6-Tetramethylpiperidine, abbreviated TMP, HTMP, or TMPH, is an organic compound of the amine class. In appearance, it is a colorless liquid and has a "fishy", amine-like odor. This amine is used in chemistry as a hindered base (hindered amine). Although TMP finds limited use per se, its derivatives are a mainstay of hindered amine light stabilizers. WebA water soluble Lemke chromophore derivative shows an unusual polarity dependence of its emission efficiency, leading to strong red-NIR fluorescence in water when fitted with appropriate water-solubilizing polymer chains. In this edge article, the synthesis of the chromophore is described. The dependence of its fluorescence on solvent polarity is … crown whitening products
