用实验结果验证了亲水两亲溶液中分子填充参数的几何规律。通过改变溶液条件改变分子填充参数，在单链亲水亲和试剂苯基-1,4-双（氧己酸）二钠（即C6PhC6Na2溶液）中成功地控制了聚集体的形态。通过改变pH和添加NaBr或辛醇，观察到胶束-囊泡-管转变。在带相反电荷的波/表面活性剂混合体系中，分子填充参数的作用与混合比例有关。
The geometrical rule of molecular packing parameters in a bolaamphiphile solution was tested with experimental results. By modifying the solution conditions to change the molecular packing parameters, the morphology of the aggregate was successfully manipulated in a single-chain bolaamphiphile, disodium phenyl-1,4-bis (oxyhexanoate) (i.e., C6PhC6Na2 solution). Micelle-vesicle-tube transformation was observed by changing the pH and the addition of NaBr or octanol. In the mixed systems of oppositely charged bola/surfactants, the molecular packing parameter's role is related to the mixing ratio.
