阴离子-离子载体加合物稳定分子内氢键可调节阴离子结合中的荧光信号从猝灭到增强；分子内氢键被认为抑制了淬灭过程，否则可能会增加阴离子加合物的构象刚性，导致对氰化物离子的荧光选择性增强，在各种阴离子中。
Fluorescence signaling in anion binding is modulated from quenching to enhancement by intramolecular H-bonding stabilization of anion-ionophore adducts; the intramolecular H-bonding is suggested to suppress the quenching processes otherwise possible and increase the conformational rigidity of the anionic adducts, leading to fluorescence enhancement in a selective fashion towards cyanide ion, among the various anions examined.
