This talk will explore the application of tetrathiafulvalene tetrathiolate (TTFtt) ligands for new coordination chemistry as well as work towards new molecular diagnostics. TTFtt is a fusion of the common organic electronic TTF unit with two dithiolene motifs which are known to support unusual physical properties. Molecular TTFtt complexes exhibit complex electronic structures with tunable diradical character. Furthermore, these complexes emit brightly in the near-IR II region which is stable to water and harsh conditions such as acid. These properties, and their interface, have many exciting applications in imaging and sensing. Preliminary in-vitro and in-vivo results support the viability of these complexes as novel diagnostic motifs.
