Synthesis and Magnetic Properties of Orthogonally Linked Phenothiazine Cation Radical Dimer and Tetramer
摘要:
A 3,3'-orthogonally linked phenothiazine cation radical dimer with methyl substituents at the 2, 2', 4, and 4' positions was synthesized. The climer was isolated as a stable product which exists in a triplet state due to a torsion angle of ca. 80 degrees between the two phenothiazine units. The tetramer was also synthesized by linking the dimers using a 1,4-phenylene spacer.
