• Anion sensing
• Hydrazide derivatives
• Highly selective detection
• Terminal substituent

Three dimeric hydrazide derivatives with nitro, phenyl, and methyl terminal substituents were synthesized and their anion responsive behaviors were studied. The UV-vis spectra showed that the compounds with methyl groups and phenyl groups can allow highly selective fluoride detection, whereas the compound with terminal nitro substituent can respond to F-, AcO- and H2PO4-, due to the distinction on acidity of compounds which is caused by electronic effect and field effect of terminal substituents. The 1H NMR spectra revealed that the anion responsive mechanism for F-, AcO- and H2PO4- was different due to the much lower basicity of AcO- and H2PO4- compared to Whereas the number of hydrazide groups and the nature of the terminal substitute do not affect the fluoride anion responsive mechanism. It demonstrates that, by altering terminal substituent groups, the anionic recognition ability of compounds could be adjusted and controlled.
