Sugar-Controlled Aggregate Formation in Boronic Acid-Appended Porphyrin Amphiphiles

摘要

Synthetic amphiphilic compounds can organize in aqueous media as fibers, lamellas, vesicular membranes, etc. Oriented molecular aggregates of amphiphilic porphyrins are of particular interest for their photoactive and redox-active functions. As pointed out by Fuhrhop et al., one may consider the porphyrin macrocycle as a unit for such assemblies as a rigid hydrophobic box with special packing properties. Furthermore, porphyrin-based amphiphiles have an advantage in that their aggregation properties can be conveniently monitored not only by electron micrographic observations but also by spectroscopic methods through the change in their charabteristic Soret and Q bands.
