Besides metallocycles, metallodendrimers, and metallo-supramolecular polymers [58], few examples of hollow supramolecular architectures have been obtained from polytopic ligands containing terpyridine units. Lehn et al. used heteroaromatic ligands with terpyridine type coordination sites to obtain cylindrical self-assembled architectures (Fig. 11) [60]. For synthesis of the cage 37, tris-2,4,6-(2-pyrimidyl)-l,3,5-triazine (35) was mixed with lead triflate in... [Pg.109]

In all of the studies summarized above, the Mebip ligands were covalently attached to a telechelic core and served either to chain-extend or cross-link these building blocks, in connection with various metal ions, into linear or cross-linked metallo-supramolecular polymers. Rowan et al. took a different approach when they blended complexes based on monofunctional dodecyl-Mebip and metal ions into methacrylate-based polymer matrices [85]. Interestingly, when complexes with platinum ions were used, a mechanically responsive material was obtained, which... [Pg.367]

The concept for the design of supramolecular liquid crystals and supramolecular polymers has opened new fields in materials and polymer science, which are ever expanding. New stable and dynamic structures are generated by self-organization of these materials. Related functional polymeric materials such as dendrimers [140-143], block copolymers [144], polymer blends [145,146], rotaxanes [147-149], anisotropic gels [150-152], metallo-supramolecular polymers [153,154], nanoobjects [155,156] as well as supramolecular polymers are also obtained by self-assembly of multicomponents through noncovalent interactions. [Pg.154]

The proper choice of stoichiometry allowed the formation of block-like arrangements or even star-shaped polymers with electroactive metal centers [209]. An interesting example is given for metallo-supramolecular polymers, which can even reversibly form gels [210-214]. Thus, supramolecular polymers can be made by use of bifunctional Unkers. Here, the redox active units are located in the main chain... [Pg.139]

An interesting example is given for metallo-supramolecular polymers, which gelate under certain conditions [387]. By electrode reactions, the gel and sol states can be switched reversibly (Fig. 39) [210]. Even silk fibroin solution can electrogelate when the local pH is altered electrochemically [388]. [Pg.164]
