Previously reported complex N1,N1-bis(thiazol-4-ylmethyl)butane-1,4-diaminetriscarbonylrhenium(I) bromide (4BT) was shown to have unusual emissive characteristics including a multiemissive profile and emission wavelength variation with excitation wavelength. This behavior at the studied timescale seems to break the Kasha-Vavilov rule, photon emission occurs in appreciable yield only from the lowest excited state of any multiplicity. To further characterize and elucidate the underlying mechanism of this unusual photophysical behavior, structural isomers of 4BT were synthesized, purified and characterized. The location of triplet states, solid state and low temperature spectroscopic measurements were carried out for 4BT. Additionally, the ligand family used to explore this photophysical behavior was platformed for use in carbonyl releasing molecules with an aim towards cytotoxicity.
