Star-shaped molecules with three mutually immiscible arms self-assemble to form a variety of novel structures, with conformations that attempt to minimize interfacial area between the domains composed of the different arms. The geometric frustration caused by the joining of these arms at a common centre limits the size and shape of each domain, encouraging the creation of complex and interesting solutions. Some solutions are tricontinuous, and these solutions (and others) share aspects of bicontinuous structures with amphiphilic assemblies as similar molecular segregation factors are at work. We describe both highly symmetric and balanced structures, as well as unbalanced solutions that take the form of intricately striped amphiphilic membranes. All these patterns can result in chiral assemblies with multiple networks.
具有三个互不相溶臂的星形分子自组装形成各种新颖结构，其构象试图最小化由不同臂组成的域之间的界面面积。这些臂在共同中心处连接所引起的几何挫折限制了每个域的大小和形状，促使形成复杂而有趣的溶液。一些溶液是三连续的，并且这些溶液（以及其他溶液）与两亲性组装体共享双连续结构的一些方面，因为类似的分子分离因素在起作用。我们描述了高度对称和平衡的结构，以及呈错综复杂条纹状两亲性膜形式的不平衡溶液。所有这些模式都可以导致具有多个网络的手性组装体。
