A ferrocene–pyrene based ‘turn-on’ chemodosimeter for Cr3+ – application in bioimaging†
Abstract
Structurally simple, ferrocene–pyrene imine dyad 1 has been developed as a ‘turn-on’ chemodosimeter for Cr3+. The sensing event is based upon the hydrolysis of the imine functionality. Further, 1, which is also non-cytotoxic (100% cell viability), detects intracellular Cr3+ in the human breast cancer (MCF-7) cells.
