Abstract

Abstract: Two colorimetric and fluorescent probes based on ferrocene derivatives have been designed and synthesized. Among studied anions (F −, AcO −, H2 PO4 −, Cl −, Br − and I − ), probe 1 with p ‐nitrophenyl hydrazine structure has the strongest binding ability for F −, as well as probe 2 for H2 PO4 − . It had strong binding ability and was not affected by other anions. The determination limit of 1 toward F − was 5.0×10 −6 mol⋅L −1 which can be used for the trace detection of F − . The interacted process of host–guest accompanied by colorimetric changes and increment in fluorescent intensity of the probes. A 1 H‐NMR titration experiment and theoretical investigation indicated that −NH in hydrazine participated in the interaction, and the hydrogen‐bonding formed between the probes and anions. These results provided an essential clue to the developing the colorimetric probe based on hydrazine participation. Abstract :
