摘要:
The effect of ''planarization'' on pi-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(2.) are reported. The corresponding dianion 6(2-), 2M+ (M = Li, K) is studied using NMR and UV-vis spectroscopy.
