4. Conclusion
In summary, a large fluorescence enhancement of DSMI was
realized by the formation of an inclusion complex with CB[6], and
the distorted cavity of CB[6] was observed in computational results.
The distorted cavity of CB[6], which exhibited inhibition of the TICT
process by restricting the rotation of the aniline ring and pyridinium
ring of DSMI, seems to be the main reason for the large
increase in fluorescence. Meanwhile, the ion-dipole interaction
between DSMI and CB[6] may make a minor contribution to the
fluorescence enhancement. A reconfigurable and resettable
molecular logic gate systemwas constructed by modulating the pH
of the solution and adding CB[6] to or removing it from the hemicyanine
dye. This study laid a solid foundation for the design of
molecular logic gates by a supramolecular interaction mode.
