| Abstract: | Two new novel ferrocenylaclyhydrazone-based receptors FcL1 and FcL2 were prepared and characterized by 1H NMR, IR, elemental analysis. X-ray crystallographic reveals that FcL1 belongs to Monoclinic system, with space group P2(1)/c, and FcL2 belongs to Hexagonal system with space group P6(5). It forms a novel helical chain by self-assembly. The electrochemical studies reveal that the formal potential (E 0) of FcL1 and FcL2 show a gradual decrease in the order Fc(Ferrocene) < FcL1 < FcL2 and FcL1 is responsive to Pb2+. The maximum electrochemical shift of FcL1 for Pb2+ is about 44 mV. FcL1 shows selective potential response to Pb(II) ion. |
