Studies of high energy particles require precise and accurate detector readings. Because many of these detector parts are made of polystyrene/polyvinyltoluene, fluorescent compounds that can undergo Excited State Intramolecular Proton Transfer (ESIPT) with suitable fluorescence characteristics and physical properties can be doped in plastic scintillators. The molecule 3-hydroxy-2-phenylchromen-4-one (3-hydroxyflavone or 3-HF) is known for its absorption near 350 nm and emission around 530 nm. With proper substitution of the phenyl ring, desired properties can be obtained. Our research focused on the synthesis and study of the mechanistic pathway of 3-hydroxy-2-phenylchromen-4-one and appropriately substituted molecules on C-2 that could potentially enhance the extinction coefficient and the solubility to ease the inclusion of such in plastic.  Purification lead to instringting mechanistic findings.
