摘要
Tunable supramolecular nanoarchitectures have received enormous attention because of their potential in materials fabrication. Herein, a variety of morphologically intriguing nanoarchitectures have been constructed from diphenanthro-24-crown-8 ether (DPC) and metal ions. SEM and TEM showed that the self-assembled nanofibers undergo a CsI -induced transformation into regular nanoribbons, and further into nanospheres and nanoparticles by the complexation of NiII and AgI ions because of the strong ion-dipole interaction. Moreover, the X-ray crystal structure determination and powder X-diffraction data further confirmed that these morphological transformations resulted from the different complexation between DPC and metal ions. This result provides a new strategy for the subtle manipulation of supramolecular assemblies.
