Modulation of nanotube packing through the controlled self-assembly of tris-p-carboxylatocalix[4]arenes

摘要

Crystallisation of tris-carboxylatocalix[4]arenes from pyridine affords self-assembled layered and triply helical nanotubular arrays; the latter of these represents a modulation of nanotubule spacing in a persistent self-assembly motif.rnControlling and modulating the self-assembly of molecular building blocks to form large non-covalent superstructures is a challenging goal in supramolecular chemistry. Large nanometre scale assemblies such as molecular capsules are being formed with greater frequency due to the elucidation of supramolecular assembly motifs, and the exploration of libraries of available (and topologically directional) building blocks.
