Abstract The heteroditopic receptor 2 containing a crown ether and amidoferrocence groups was synthesized and the binding abilities with various anions are reported in the presence and absence of metal cations. In the presence of Na + , 2 showed positive co-operative binding towards Br − with the binding affinity K ass  = 16,096 M −1 . Therefore, receptor 2 showed a switched-on binding for Br − in the presence of Na + and a switched-off binding in the absence of Na + . Compound 2 was also found… CONTINUE READING
