Description

<jats:title>Abstract</jats:title> <jats:p>Simultaneous formation of two types of 1:1 complexes of 6-(4-methylphenylamino)-2-naphthalenesulfonate (6,2-TNS) with heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin (TMCD) in solution was detected by fluorescence spectroscopy. Fluorescence titration supported the formation of 1:1 complexes. However, the observed fluorescence spectrum was resolved into two components by time-resolved spectroscopy.</jats:p>
