abstract = "We report highly unusual photophysical properties of a fac-Re(CO)3–bisthiazolate complex, which is shown to break Kasha's rule. Herein, we show that such a complex has unusual emission wavelength variation due to the presence of photo-induced isomerization from the stable, ground-state N,N-bound thiazolatecomplex to S,N- and S,S-donation in the photo-induced excited state. A triple excitation, triple emission profile along with extensive DFT calculations support this theory to showcase an unusual circumstance of sulphur donation to the fac-Re(CO)3 core upon luminescence. fac-Rhenium tricarbonyl complexes areextensively studied due to their fluorescent properties, high stability, and ready incorporation into conjugates with broad applicability in imaging and targeting. The spectroscopic features of the complex under study have broad fundamental interest while also offering potential for design of novel agents for use in biological imaging studies.",

N2 - We report highly unusual photophysical properties of a fac-Re(CO)3–bisthiazolate complex, which is shown to break Kasha's rule. Herein, we show that such a complex has unusual emission wavelength variation due to the presence of photo-induced isomerization from the stable, ground-state N,N-bound thiazolatecomplex to S,N- and S,S-donation in the photo-induced excited state. A triple excitation, triple emission profile along with extensive DFT calculations support this theory to showcase an unusual circumstance of sulphur donation to the fac-Re(CO)3 core upon luminescence. fac-Rhenium tricarbonyl complexes areextensively studied due to their fluorescent properties, high stability, and ready incorporation into conjugates with broad applicability in imaging and targeting. The spectroscopic features of the complex under study have broad fundamental interest while also offering potential for design of novel agents for use in biological imaging studies.
