Article Description

Four new Mn(I)–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 photo-theranostics.
