A porphyrin tripod (PZnT) composed of three zinc porphyrin wings connected via triazole bridges was prepared as a monomeric building block for a supramolecular polymer. PZnT formed long fibrous supramolecular polymers with a diameter of 7 nm through the axial coordination of triazole nitrogen atoms to zinc porphyrins. The molecular packing structure of a PZnT-based supramolecular polymer was assigned as a hexagonal columnar phase. PZnT formed a stable 1:1 host-guest complex with 1,3,5-tris(4-pyridyl)benzene (Py3B) through axial coordination of pyridyl groups to zinc porphyrins. The host-guest complex between PZnT and Py3B adopts a cone-shaped geometry. After the addition of Py3B, the host-guest complex exhibited a characteristic X-ray diffraction pattern of rectangular columnar ordering. Furthermore, the formation of supercoiled helical fibrous assemblies was observed by transmission electron microscopy (TEM).

(Figure Presented) Self-assembly of a C3v 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 C60 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.
