probe compounds

Flavonol (3-Hydroxyflavone) is a member of the class of compounds known as flavonols. 3-hydroxyflavone can be found in a number of food items such as brassicas, pomegranate, red raspberry, and fenugreek. 3-hydroxyflavone is a chemical compound. It is the backbone of all flavonols, a type of flavonoid. It serves as a model molecule as it possesses an excited-state intramolecular proton transfer (ESIPT) effect to serve as a fluorescent probe to study membranes for example or intermembrane proteins.

trans-4-(Trifluoromethyl)cinnamic acid is a photosensitizing compound. It is used as a reagent in the synthesis of various compounds, such as heterocyclic compounds and pharmaceuticals. It has also been used as a catalyst for organic reactions such as the Heck reaction and the Suzuki-Miyaura reaction. It is also used as a fluorescent probe in biological studies to detect and monitor various biomolecules.
