Oligo(9,10‐anthrylenes), Organic Compounds with Stable High‐Spin States

Abstract

According to ESR spectroscopy and cyclic voltammetric experiments the soluble oligo (9,10-anthrylenes) 1 are unusual redox systems. Significant for the development of organic ferromagnets is the formation of high-spin states in such ions, which can carry one charge per anthracene unit. Even the heptamer 1 (R = n-hexyl, m = 2) was isolated in 18% yield.
