The fabrication of complex hierarchical heterostructures with π-electronic nanomaterials has attracted the interest of many researchers because the functions and properties of the resulting nanomaterials are related to their length-size distribution. Here, a complex multi-dimensional hierarchical heterostructure created via a sequential 2D seeded self-assembly is reported using a series of small organic molecules (1–3). Interestingly, we first discovered that the amount of kinetically trapped off-pathway aggregates could affect the dimension of the heterostructure. The co-assembly method was used to develop seeds with controlled luminescence that changed from blue to yellow emission to increase the complexity of the hierarchical heterostructure. Different luminescent seeds can induce the formation of hierarchical heterostructures possessing different luminescence properties. This strategy can then be extended to fabricate other complex hierarchical heterostructures from small organic molecules.

通过种子自组装制造具有受控发光的复杂分层异质结构

用 π 电子纳米材料制造复杂的分层异质结构引起了许多研究人员的兴趣，因为所得纳米材料的功能和性质与其长度-尺寸分布有关。这里，创建了一个复杂的多维分级异质结构通过一顺序2D接种自组装使用一系列有机小分子的报道（1-3）。有趣的是，我们首先发现动力学捕获的路径外聚集体的数量会影响异质结构的尺寸。共组装方法用于开发具有受控发光的种子，该种子从蓝色发射到黄色发射，以增加分层异质结构的复杂性。不同的发光种子可以诱导具有不同发光特性的分层异质结构的形成。然后可以扩展该策略以从有机小分子制造其他复杂的分层异质结构。
