摘要：

The inclusion complexes of tetracyanoresorcin[4]arene with six quaternary ammonium cations-biologically important acetylcholine and choline, tetramethyl ammonium, tetraethyl ammonium, tetrapropyl ammonium and tetrabutyl ammonium-were studied by means of electrospray ionization mass, fluorescence and NMR spectrometries. The results indicate that tetracyanoresorcin[4]arene shows high affinity toward these ammoniums and is capable of recognizing their sizes.
