通过使用带有单个烷氧基胺侧链的多功能苯并菲中间体，已经实现了一种简单的合成三苯基-二萘嵌苯-苯并菲三单元结构。其中，PBITP 10显示出稳定的柱状中间相，这意味着在结构中有利地匹配核-核分离。重要的是，三元组可以用作媒介物，用于掺杂具有功能性但不相容的二萘嵌苯单元的柱状苯并菲基质，并且掺杂有0.1%PBITP 10的六己氧基苯并菲基质的混合物是均匀的和液晶的。
A straightforward synthesis of triphenylene-perylene-triphenylene triad structures has been achieved by using versatile triphenylene intermediates bearing a single oxyalkyl amine side chain. Among these, PBITP10 showed a stable columnar mesophase implying favorably matched core-core separations in the structure. Importantly, the triad can be used as a vehicle for doping columnar triphenylene matrices with functional but incompatible perylene units and a mixture of hexahexyloxytriphenylene matrix doped with 0.1% PBITP10 is homogeneous and liquid crystalline.
