An intramolecular charge-transfer (ICT) compound, (TCBD)2OPV3, has been synthesized and fabricated into one-dimensional nanotubes by a reprecipitation method. The observation of SEM and TEM showed the nanotubes were formed from their zero-dimensional precursors of hollow nanospheres. Reconstruction was found to happen during the morphology transition progress. The morphology transition and reconstruction are proposed to be a "curvature strain releasing" process driven by donor-acceptor dipole-dipole interactions. An aggregation-induced emission (AIE) effect was observed for (TCBD)2OPV3. Both aggregates of vesicles and nanotubes were observed to be good red emitters with near-infrared end emission of 750-850 nm, which endows the material with potential applications in the fields of optical devices, biosensors, and biolabels.
一种分子内电荷转移（ICT）化合物（TCBD）2OPV3已通过再沉淀法合成并制备成一维纳米管。扫描电子显微镜（SEM）和透射电子显微镜（TEM）观察表明，纳米管由其空心纳米球的零维前体形成。发现在形态转变过程中发生了重构。形态转变和重构被认为是由供体-受体偶极-偶极相互作用驱动的“曲率应变释放”过程。观察到（TCBD）2OPV3具有聚集诱导发光（AIE）效应。囊泡和纳米管的聚集体均被观察到是良好的红色发射体，近红外发射端在750-850nm，这赋予了该材料在光学器件、生物传感器和生物标记领域的潜在应用。
