diquinones and diimides were produced electrochemically and studied by ESR. The odd electron of substituted 1,4,8,11-pentacenetrone anion radicals is localized (in a naphthoquinoid unit) and hops from one quinone to the other. The hopping rate was measured. The anion radicals of similarly sized anthracenetetracarboxylic acid 2,3:6,7-diimides have a delocalized odd electron, and there is relatively high electron
线性多并苯二醌和二酰亚胺的阴离子自由基电化学产生并通过ESR研究。取代的 1,4,8,11-并五苯酮阴离子自由基的奇数电子被定位(在萘醌单元中)并从一个醌跳跃到另一个。测量跳跃率。类似大小的蒽四甲酸2,3:6,7-二亚胺的阴离子自由基具有离域奇数电子,桥上有较高的电子密度。结果与其他非共轭双电泳阴离子自由基比较
