Abstract

The effect of “planarization” on π-conjugated 1,3-connected polyarylmethyls in connection with the electronic structure and magnetic properties is examined. The synthesis, ESR and UV-vis spectroscopy, voltammetry, and magnetic studies of triplet diradical 6 are reported. The corresponding dianion 62−, 2M+ (M = Li, K) is studied using NMR and UV-vis spectroscopy.
