(hydroxypropyl-

showed lower absorption than the sum of the individual spectra. Also, changes in fluorescence were observed by adding the macrocycles, quenching with

. The higher fluorescence enhancement was with
rationalized as a complex formation with 1:1 stoichiometry, with an average value for the association constant (
) of (12 ± 1) x 10
M
, and a quantum yield ratio between the complexed
and free
(Φ
/Φ
) of (1.56 ± 0.02) at neutral pH and 25.0 °C. These increases in fluorescence were used as an on-fluorescence switch to develop a supramolecular analytical method for
in aqueous samples. The best analytical parameters were in
(LOD = 1.41 ± 0.01 ng mL
). The method was validated in aqueous samples of river and tap water with recoveries between 96%-104%. The proposed supramolecular method is quick, direct, selective and represents an alternative and low-cost analysis method. |
