Organic high-spin systems: Synthesis, electrochemical and spectroscopic studies of π-extended tetraaryl m-phenylenediamines

Three highly π-extended tetraaryl-1,3-phenylenediamines for charged high-spin molecular systems were successfully synthesized using Suzuki coupling. Their electrochemical and spectroscopic properties were also examined. They showed blue fluorescence. The dications derived from highly π-extended tetraaryl-1,3-phenylenediamines were generated and characterized by electron transfer stopped-flow method.

A series of highly π-extended tetraaryl-m-phenylenediamines were designed and synthesized as a precursor of positively charged high-spin systems. The electrochemical and spectroscopic properties were examined.Figure optionsDownload as PowerPoint slide
