The synthesis of new biological and polymeric supramolecular synthons and their assembly into unique supramolecular architectures is presented. These new supramolecular synthons are functionalized with ligands that compliment metallated pincer complexes. Through the use of ditopic metallated pincer complexes these supramolecular synthons can be self-assembled into infinite linear chains. The first class of supramolecular synthons synthesized were based on cyclic peptide units, by embedding a pyridyl unit into the side-chain of one of the peptide residues the cyclic structure can be coordinated to a metallated pincer complex. It is proposed that these supramolecular architectures may be further enhanced by incorporating multiple pyridyl units along the cyclic peptide backbone and coordinating them through multitopic pincer complexes to give porous membrane structures. The second class of supramolecular synthons is based on photoluminescent X-shaped cruciform molecules. By terminating one axis with pyridyl moieties these units may be assembled into fluorescent coordination polymers with good solution processable characteristics. This work is concluded with several synthetic routes to overcome the current limitations of our first generation of cruciform coordination polymers and cyclic peptide structures.
