Supramolecular chemistry has seen a burgeoning interest over the last few decades for the fascinating findings that lie beyond the molecule. Supramolecular chemistry can also offer a fresh interface with biological and materials science. My research project is focused on designing, synthesizing, and exploring the intrinsic properties of complexes based on cobalt, rhodium, and platinum. In each case, thiourea/guanidine derivatives are our ligands of choice to confer H-bonding sites for second-sphere coordination of guest molecules. Second-sphere H-bonding interactions with three different guest molecules were analyzed to obtain association constants (K[subscript a] values) from ~ 10[superscript 2] M[superscript-1] to ~10[superscript 4] M[superscript -1] via UV-vis titration studies. Five sets of single crystal X-Ray diffraction data of our novel complexes were also acquired, alongside the result of a thermochromism test of one of our cobalt complexes. Obtained interesting features include self-recognition and self-assembled structures. Overall, six novel thiourea/guanidine ligand-containing complexes – two for each of cobalt (II), rhodium (III) and platinum (II) - were synthesized. Through these dynamic H-bonding interactions, we see potential applications of our molecules across the fields of medicine, biology, agriculture, and more. Our Host-Guest studies prove that these complexes are able to bind with DNA nucleobase-like molecules via hydrogen bonding, meaning that anticancer assays of our platinum (II) and rhodium (III) thiourea/guanidine-containing compounds are promising avenues for future evaluation. Results of dilution studies show potential supramolecular oligomer structures formed in dynamic system. Finally, testing our compounds within the arena of organometallic catalysis for specific reactions is also promising work that lies ahead.
