A supramolecule composed of two phthalocyanine dimer radicals linked by a pivot joint: Synthesis of mono-15-crown-5-substituted bis(phthalocyaninato)lutetium

摘要

Mono-15-crown-5-substituted bis(phthalocyaninato)lutetium was synthesized. By addition of potassium cation in solution, the phthalocyanine dimer radical formed a supramolecular structure which preserves two unpaired electrons and shows a ESR signal of a triplet state. From observed zero field splitting constant, the structure is likely to be bent rather than straightly linked. [References: 11]
