Quantum computing is quickly becoming a familiar topic, with companies such as Google frequently appearing in the news for developing the next best quantum computer. Information processing in a quantum computer relies on the manipulation of electron spins in a quantum bit (qubit), the essential piece of a quantum computer. Significant research for developing molecular qubits has focused on complexes with high magnetic blocking temperatures, as this measurable property directly corresponds to information storage. The anionic terbium (III) lanthanoid diphthalocyanine complex ([TbPc2]-) was one of the first lanthanoid single molecule magnets with a blocking temperature of 522 cm-1, and has since become the most studied of the molecular qubit candidates. Since this discovery, significant research has gone into the study of various lanthanoid (III) diphthalocyanine complexes, in an effort to improve the magnetic blocking temperature. Synthesis is accomplished via a one-pot reaction with a phthalonitrile derivative, a lanthanoid salt, and a reducing base. This methodology was utilized here to synthesize a variety of halogenated lanthanoid (III) diphthalocyanine complexes, which has been largely unexplored thus far. While some iodine-substituted complexes have been previously prepared, they were never fully characterized, and often were present as a mixture of isomers. Here we describe the stucture of well-defined halogenated complexes, and the study of the impact of the nature and position of halogen substituents on their magnetic properties.
