Dynamics of pyrenesemicarbazide and pyrenethiosemicarbazide in reverse micelle of AOT in n-heptane: Probing critical penetration of water molecules toward the palisade

In the present work, we have introduced two similar probe molecules with pyrene tags that can reside in different positions in the reverse micelles and show opposite dynamism on excitation. Herein, we have changed the concentration of water in the reverse micellar core gradually and monitored the spectrochemical changes in the dynamism of the two designed probe molecules. The results indicate that water molecules penetrate through the interface of the reverse micelles up a certain critical amount.
