Designing and preparing supramolecular fluorescent probe based on carminic acid and γ-cyclodextrins and studying their application for detection of 2-aminobenzidazole
Supramolecular fluorescent probe, which was designed and modeled from carminic acid (CA) and γ -cyclodextrins ( γ -CDs), was initially qualified and stated comprehensively. Fluorescence intensity of CA could be dramatically enhanced ∼850 a.u. through formation of a supramolecular fluorescent probe CA@ γ -CDs. The super-probe was verified by geometric conformation and molecular docking, and subsequently characterized by FT-IR, NMR, XRD and fluorescence lifetime. Furthermore, the CA@ γ -CDs probe was proved on the detection of fungicide 2-aminobenzidazole (2-BZ). Finally, fluorescence performance of CA and the application of the probe for molecular recognition were both motivated by γ -CDs significantly, which could facilitate the fluorescence detection of CA more extensively and precisely.
