摘要:
A series of substituted alkali metal benzophenone ketyls was prepared and studied by ESR at low temperature. These species form triplet radical pairs in THF solution. Zero-field splitting parameters show that the high-spin behavior of these systems is unaffected by a variety of electronically and sterically perturbing substituents. The use of ketyl radical pairs as building blocks in the construction of molecular magnetic materials is suggested.
