Fluorescent detection of polycyclic aromatic hydrocarbons in ternary cyclodextrin complexes
Reported herein is a new method for the detection of polycyclic aromatic hydrocarbons
(PAHs) which relies on energy transfer from the PAH to a near-infrared emitting squaraine
fluorophore. This energy transfer occurs inside the γ-cyclodextrin cavity, with up to 35%
emission observed from energy transfer compared with exciting the squaraine directly.
