Design, synthesis and properties of one dimensional oligoaryltriamine high-spin molecule precursors with plural alkyl groups on the central ring

Abstract

A series of one dimensional triamine with various substituents at the central aromatic ring were designed and synthesized. Electrochemical and novel electron transfer stopped-flow (ETSF) methods were invoked for characterizing the absorption spectra of the corresponding short-lived mono- and dicationic states. Useful molecular design rules for stabilizing the di and tricationic states were elucidated.
