基于六苯基苯和四苯基甲烷支架成功地分离出稳定的(和可溶的)六-和四-三苯甲基阳离子已经通过使用容易获得的起始原料完成。这些坚固的聚三苯甲基阳离子可以结晶形式分离,并可以在0°C下无限期保存。它们的结构已通过1 H / 13 C NMR光谱和UV-vis光谱确定。这些聚三苯甲基阳离子的结构通过从三乙基硅烷,环庚三烯或硼烷-二甲基硫醚络合物的氢化物转移进行定量转化为还原的(聚)三苯甲基衍生物而得到进一步证实。

A versatile synthesis of a dendritic structure (5) is described in which six tetraphenylethylene moieties are connected to a central benzene ring in such a way that one of the phenyl rings of each tetraphenylethylene is also part of the propeller of the hexaphenylbenzene core. Observation of multiple oxidation waves in its cyclovoltammogram as well as an intense charge-resonance transition in the near-IR region in its cation radical spectrum suggests that a single hole delocalizes via electron transfer over six identical redox-active centers.

The successful isolation of stable (and soluble) hexa- and tetratrityl cations based on hexaphenylbenzene and tetraphenylmethane scaffold has been accomplished by using readily available starting materials. These robust polytrityl cations can be isolated in crystalline form and stored indefinitely at 0 °C. Their structures have been established by 1H/13C NMR spectroscopy and by UV−vis spectroscopy
