Extensive investigation on self-assembly of DDAB in aqueous medium is severely restricted due to its insolubility. However, DDAB is highly soluble in acetonitrile, which allows investigation in a wide range of concentrations. An unusual aggregation phenomenon is exhibited by DDAB in acetonitrile, displaying six breaks in conductivity-concentration profile in a wide concentration regime. This study along with that of steady state fluorescence measurements indicate the presence of six-step self-assembly phenomena to occur in the system. HRTEM experiments show the presence of fascinating morphologies of the aggregates. The experimental observations are analyzed and the driving forces behind the phenomena are discussed.

DDAB在水介质中自组装的广泛研究由于其不溶性而受到严格限制。但是，DDAB在乙腈中的溶解度很高，因此可以在很宽的浓度范围内进行研究。DDAB在乙腈中表现出一种异常的聚集现象，在宽浓度范围内电导率-浓度曲线出现了六个断裂。这项研究以及稳态荧光​​测量表明，系统中存在六步自组装现象。HRTEM实验表明，聚集体具有令人着迷的形态。分析了实验观察结果，并讨论了现象背后的驱动力。
