星形低聚亚苯基亚乙烯基（OPV）介晶是形状持久的，并具有形式上大的空隙空间。具有三个苯乙烯重复单元的介晶以柱状螺旋排列密集堆积。一个富勒烯通过一个短的间隔物的附件的中间相稳定性的异常增加的结果。X射线散射和模型证明了一种三螺旋结构，其中富勒烯完美地填充了星星介晶臂之间的空隙。
Star-shaped oligophenylenevinylene (OPV) mesogens are shape-persistent and possess formally large void space. A mesogen with three styrene repeating units packs densely in a columnar helical arrangement. Attachment of one fullerene through a short spacer results in an exceptional increase of the mesophase stability. X-ray scattering and modeling evidence a triple-helical arrangement in which the fullerene perfectly fills the void space between the arms of the star mesogen.
