Organic heterostructured micro-/nanomaterials (OHTMs) integrating heterostructured advantages and organic material character have drawn strong attention in nanoscience and nanotechnology to meet the ever-increasing technological requirements. However, the fine synthesis of OHTMs with high spatial/angular characteristics remains challenging because of the complex epitaxial relationships of material combinations. Herein, we develop a rational sequential self-assembly strategy to synthesize the OHTMs composed of m-BCB or o-BCB one-dimensional (1D) microrods or microbelts as trunks and TPBe 2D microplates as branches via regulating the π–π interaction intensity (|Eo-BCB = −25.56 kcal mol–1| > |Em-BCB = −15.49 kcal mol–1| > |ETPBe = −5.06 kcal mol–1|). Notably, both the lattice matching and the surface–interface energy balance prefer heterogeneous nucleation and epitaxial growth of the branch part on the surfaces of the preformed seed trunk part. Our sequential self-assembly approach demonstrates a universal avenue to precisely synthesize the OHTMs in a desired mode, which provides promising candidate for the integrated optoelectronics.

由低维微晶组成的有机异质结构的顺序自组装
结合异质结构优势和有机材料特性的有机异质结构微/纳米材料（OHTM）在纳米科学和纳米技术中引起了极大的关注，以满足不断增长的技术要求。然而，由于材料组合的复杂外延关系，具有高空间/角度特性的OHTM的精细合成仍然具有挑战性。本文中，我们开发了一种合理的顺序自组装策略，以通过调节π-π相互作用强度来合成由m -BCB或o -BCB一维（1D）微棒或微带作为主干和TPBe 2D微板作为分支的OHTM（ | E o -BCB = −25.56 kcal mol –1 |> | Em -BCB = −15.49 kcal mol –1 | > | E TPBe = −5.06 kcal mol –1 |）。值得注意的是，晶格匹配和表面-界面能量平衡都倾向于在预成型种子主干部分的表面上分支部分的异质成核和外延生长。我们的顺序自组装方法展示了一种以所需模式精确合成OHTM的通用途径，这为集成光电技术提供了有希望的候选人。
