    "abstract": "We discuss the relations between the violation of the CHSH Bell inequality\nfor systems of two qubits on the one side and entanglement of formation, local\nfiltering operations, and the entropy and purity on the other. We calculate the\nextremal Bell violations for a given amount of entanglement of formation and\ncharacterize the respective states, which turn out to have extremal properties\nalso with respect to the entropy, purity and several entanglement monotones.\nThe optimal local filtering operations leading to the maximal Bell violation\nfor a given state are provided and the special role of the resulting Bell\ndiagonal states in the context of Bell inequalities is discussed.",
