描述了柱状相的诱导，其中本质结晶的1,4,6,9-四酰基氧基芘与四硝基芴酮（TeNF）混合作为电子受体。具有线性壬基链的芘衍生物PC9没有显示出任何使用三硝基芴酮的中间相，这表明TeNF倾向于更强的电荷转移相互作用。取代基的形状控制了中间相的类型：PC9和TeNF的混合物形成了矩形柱状相，而带有分支侧链的圆形衍生物则形成了六角形柱状相。
The induction of the columnar phase is described in which intrinsically crystalline 1,4,6,9-tetraacyloxypyrenes have been mixed with tetranitrofluorenone, TeNF, as an electron acceptor. The pyrene derivative with linear nonyl chains, PC9, has not shown any mesophases using trinitrofluorenone, suggesting that stronger charge transfer interaction is favored by TeNF. The shape of the substituents works to control the mesophase type: the mixture of PC9 and TeNF has formed a rectangular columnar phase, and a hexagonal columnar phase is attained by rounder derivatives bearing branched side chains.
