Aqueous solubilization of photochromic compounds by bile salt aggregates

摘要

Bile salts form aggregates in aqueous solutions which were shown to efficiently solubilize aqueous insoluble photochromic compounds. Photochromic switching was observed for a spiro-pyran and a diarylethene. In the case of the spiropyran, the incorporation into the bile salt aggregate led to improved hydrolytic stability and changes in thermal rate constants.
