2,2,2-Triphenylacetic Acid is used in preparation of Rhodium(II) Tetramethyl-benzenedipropioate complex, other Carboxylate complexes, and their catalytic activity. | [Application]
Triphenylacetic acid could be used to seal dye molecules within MOF-5. Introducing triphenylacetic acid (TPAA) capping groups traps organic dyes such as crystal violet (CV) within the MOF crystals. Surface-bound TPAA groups block the MOF pores, preventing the encapsulated dye from diffusing into the solution. Liberating the TPAA from the surface by protonation can reverse guest trapping, but acidic conditions can also degrade the MOF by extruding the carboxylate struts. In addition, triphenylacetic acid could inhibit microsomal bilirubin UDPglucuronosyltransferase activity in rat liver. This compound competitively inhibits bilirubin UDP-glucuronosyltransferase with respect to bilirubin[2-3].
