Rhodamine tethered 1,1’-unsymmetrical ferrocene functionalization: Metal sensing, cell imaging and logic gate properties

Selective funtionalization of ferrocenyl species with fluorescent active rhodamine moiety using a solvent free solid state method led to the synthesis of 1,1’- unsymmetrical ferrocene based turn-on fluorescent hydrazone molecular system, 1,1’-[CH3C(O)(η5-C5H4)Fe{(η5-C5H4)C(CH3)N-NC(O)-X}], (X = Rhodamine-6G) (1) and 1,1’-[HC(O)(η5-C5H4)Fe{(η5-C5H4)C(H)N-NC(O)-X}], (X = Rhodamine-6G (2), Rhodamine-B (3)). The unsymmetrical molecular system was...
