Herein we present organic mixed-valence compounds with an innovative H-shape design, where four redox centres are bridged "vertically" via a dibenzofulvene backbone and "horizontally" via a bis-(dibenzofulvene)-thiophene bridge. These compounds are easily oxidized to stable highly charged radical species which show intense intervalence charge transfer transitions in the near infrared region. Interestingly, depending on the position of the arylamine substituents on the bridge, both vertical and horizontal electron transfer pathways can be optically induced.
在此，我们展示了具有创新H形设计的有机混合价化合物，其中四个氧化还原中心通过二苯并富烯主链“垂直”桥连，并通过双（二苯并富烯）噻吩桥“水平”桥连。这些化合物易于氧化为稳定的高电荷自由基物种，在近红外区域显示出强烈的价间电荷转移跃迁。有趣的是，根据芳胺取代基在桥上的位置，垂直和水平电子转移途径均可被光诱导。
