title: [Interaction between cucurbit[n]urils (n = 7 and 8) and 2-amino-phenyl-thiazole].
abstract: The interaction between cucurbiturils(Q[7], Q[8]) and the 2-amino-benzothiazole (g) was investigated by 1H NMR spectroscopy, electronic absorption spectroscopy and fluorescence spectroscopy. The results show that with 2 < pH < 9, using different spectrum methods was able to observe the interaction between the cucurbit[n]urils and the guest at pH between 2 and 9, Q[7] interacts with the guest with a 1 : 1 host : guest ratio, and Q[8] interacts with the guest with a 1 : 2 host : guest ratio. Also, the inclusion constant and the thermodynamic parameters of the interaction systems, such as the entropy and enthalpy of systems, were considered.
