1.Hierarchical self-assembly of amphiphilic building blocks into various supramolecular architectures

By Shib Shankar Dash

Pages : 1-4

Molecular self-assembly is a process to obtain a well defined structure from suitable starting materials. The study of self-assembly provides a fundamental understanding of the driving forces and co-operative interaction behind these processes. In this review, the hierarchical self-assembly of amphiphilic molecules into various supramolecular architectures such as vesicles, spheres, flowers, tubes and fibrillar networks of nano- to micrometer dimensions and gels have been discussed.

Previously we have reported the spontaneous self-assembly of renewable nano-sized oleanolic acid in aqueous-organic binary solvent mixtures to form vesicles (B. G. Bag and K. Paul, Asian J. Org. Chem., 2012, 1, 150 – 154). Herein, we report the critical vesicular concentration (cvc) of oleanolic acid in DMSO-Water at varied ratio. The cvc’s determined by fluorescence spectrophotometry using hydrophobic pyrene as a fluorescence probe in 2:1, 1:1 and 1:4 DMSO-water mixture were 83, 73, 47 micro
