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.
星形寡聚苯乙炔（OPV）介晶具有形状保持性和大的空穴空间。具有三个苯乙烯重复单元的介晶在柱状螺旋排列中紧密堆积。通过短间隔物连接一个富勒烯，会导致介晶相稳定性的异常增加。X 射线散射和建模证明了三重螺旋排列，其中富勒烯完美地填充了星形介晶臂之间的空隙。
