24. 3 (10 mM) was taken in a test tube (internal diameter: 0.8 cm, length: 7.5 cm). Then 200 μL of a solution of sodium cholate (30 mM) was added to it quickly. A white precipitate appeared instantaneously and the mixture turned turbid. On sonication this turbid solution turned into a translucent gel. For more details of the gel formation see ESI.
25. The gelation process was thermally irreversible and the gel was found to be thixotropic in nature.
26. The concentration of pyrene in the sodium cholate solution (30 mM) was determined from the absorbance at 338 nm using the molar extinction coefficient of the same band in MeOH.

We have also observed Tb and Tb/Eu luminescence with an appropriate naphthalene-based sensitizer. These results will be published elsewhere.
