Received Date: 18 July 2005

The blue color system of supramolecular assembly formed by di(hydroxymethyl)di-(2-pyrrolyl)methane and tetracyanoquinodimethane (TCNQ) may be used for effective and selective detection of aniline through the visual color change in CH₃CN/H₂O mixed solvent. The excellent properties of the system make the supramolecular assembly to be a highly selective colorimetric probe for aniline.
