Welcome to Xi's group.
 Amphiphiles can self-organize into micellar structures with defined sizes and shapes that
may be used as templates for making nanostructured materials and mimicking biomineraliza-
tion processes. While the micellar structures are inherently dynamic and fluidic, an engineering
robustness is required to make these applications practical. To solve this problem, we have
proposed different way to enhance the stability of the surface micelles either by increasing the
intermolecular interaction or by polymerization in micelles, leading to development of new
ways to surface patterning.
 One of the molecular bases for self-assembly is amphiphilicity. It means that one can
control the self-assembly in a way by tuning the amphiphilicity of the building blocks. We have
used supramolecular approach and reversible chemical reactions to control the amphiphilicity,
and realized molecular self-assembly as well as disassembly. For example, we have
introduced photo-responsive groups into the building blocks and synthesized some supra-
molecular amphiphiles. An interesting finding is that these supramolecular amphiphiles can
self-organize into photo-responsive aggregates exhibiting different morphologies or properties
upon the UV irradiation. Based on our previous works in this area, we are invited to write a
review article on Adv. Mater.(2009, 21, 2849), which covers the methods of tuning the
amphiphlicity of the building blocks to control the assembly and disassembly of
supramolecular systems. This line of research on the supramolecular amphiphiles which are
constructed by supramolecular interactions will further broaden the application of the
controllable, reversible supramolecular systems.
