Supramolecular Multicomponent Self-Assembly of Shape-Adaptive Nanoprisms: Wrapping up C60 with Three Porphyrin Units
摘要:
Self-assembly of a C(3v) symmetric trisphenanthroline and linear bisterpyridines in the presence of Cu(+) did not furnish the expected supramolecular nanoprisms in quantitative yield. With an accurately sized tripyridine as a stabilizing template, the nanoprism formed exclusively. Furthermore, an adaptive constriction of the nanoprism was seen with C(60) as template: as a result of the smaller size of C(60) the nanoframework wrapped up around the guest like an accordion-type host system.

The quantitative, single step, self-assembly of a shape-persistent, three-dimensional C3v-symmetric, triptycene-based tris-terpyridinyl ligand initially gives a platonic-based cubic architecture, which was unequivocally characterized by 1D and 2D NMR spectroscopy, mass spectrometry, and single crystal X-ray structural analysis. The unique metal–ligand binding properties of the Cd2+ analogue of this
