Abstract: Methods for synthesizing and purifying 2-aryl-3,3-bis(4-hydroxyaryl)phthalimidine compounds are provided. The method includes heating a reaction mixture including a phenolphthalein, a primary aryl amine, and an acid catalyst to form a phthalimidine; precipitating the phthalimidine from the reaction mixture to provide a crude phthalimidine; providing a solution including the crude phthalimidine, an additive, and at least one solvent; contacting the solution with one or more purification agents to provide a treated solution; precipitating and recovering a phthalimidine adduct from the treated solution; and recovering a purified phthalimidine compound from the adduct.

Abstract: The invention relates to a metallocene complex according to formula (1) wherein M is a metal selected from lanthanides or transition metals from group 3, 4, 5 or 6 of the Periodic System of the Elements, Q is an anionic ligand to M, k is the number of Q groups and equals the valence of M minus 2, Z1, Z2, Z3 and Z4 are identical or different and can be chosen from the group consisting of hydrogen and a hydrocarbon radical with 1-20 carbon atoms, and adjacent substituents Z can form a ring system together with the carbon atoms of the Cp ring to which they are bound.
