文摘

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 wereformed from their zero-dimensional precursors of hollow nanospheres. Reconstruction was found to happen duringthe morphology transition progress. The morphology transition and reconstruction are proposed to be a "curvaturestrain 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 goodred emitters with near-infrared end emission of 750-850 nm, which endows the material with potential applicationsin the fields of optical devices, biosensors, and biolabels.
