Four new Mn(l)-carbonyl complexes of general formula, [Mn(L)(CO)(3)] (1 4) where L = 2-(benzo[d] thiazol-2-yl)phenol (L-1), 2-(benzo[d]thiazol-2-yl)-4,6-di-tert-butylphenol (L-2), 2-(2-hydroxyphenyl)-3H-anthra[1,2-d]imidazole-6,11-dione (L-3) and 2-(3,5-di-tert-butyl-2-hydroxyphenyl)-3H-anthra[1,2-d] imidazole-6,11-dione (L-4) rapidly release CO cooperatively on activation with visible light accompanied by a visual change in luminescence properties of the complexes allowing us to track photo-activated CO release in HeLa cells. CO-induced photocytotoxicity by the complexes was also studied in HeLa cells. Photo-activated CO release and mechanism was spectroscopically and theoretically probed. Overall, Mn(I)-carbonyls with theranostics properties are potentially emerged as the next-generation phototheranostics. (C) 2019 Published by Elsevier Ltd.
