The underlying mechanism of the unusual emissive behavior of [Re(CO)3-1,1-bis-4-thiazole-(1,4)-diaminobutane] bromide (4-BT) has been investigated. Synthesis and spectroscopic characterization of structurally similar isomers [Re(CO)3-1,1-bis-2-thiazole-(1,4)-diaminobutane] bromide (2-BT) and the location of triplet states, solid state and low temperature spectroscopic measurements, and DFT calculations show that the photophys. properties are not due to photoisomerization as previously hypothesized. The results show that the unusual emissive behavior is not observed in structural isomers, is specific to the previously reported complex, 4-BT, and may arise from vibrational energy relaxation and vibrational cooling. Translation of the unusual emissive behavior to the solid state offers an interesting platform allowing this complex to be potentially utilized as a probe, sensor or photonic device.
