摘　　要：One dimensional(1D)organic axial micro/nanocrystals serving as the building block towards integrated nanostructures have been demonstrated in various nanosystems[1-3].As an emerging solidstate platform,these micro/nanostructures are increasingly being regarded as potential candidates for constructing optoelectronic circuits.Despite remarkable achievements,pioneering works simultaneously revealed the shortage of non-guidance for molecular nucleation in these 1D axial micro/nanostructures[4-6],posing a great challenge for the practical applications.From this perspective,there is urgent to develop special 1D axial micro/nanostructures to promote the generation of highly ordered integrated structures.一维有机轴向微/纳米晶体作为构建复杂纳米结构的基石已在多种纳米系统中得到证实.尽管取得了显著的成就,但先前的工作同时揭示了这些一维轴向微/纳米结构中分子成核的有序性不足,这给实际应用带来了很大的挑战.本文提出了在一维有机轴向微米结构中引入基于分子重排的孪生变形现象,其弯曲(~50°)形成的相对活性表面为晶体的进一步外延生长提供了潜在的成核位点.此工作将促进高度有序的集成微/纳米结构的基础研究和实际应用方面的发展.
