Welcome to Xi's group.
 Supra-amphiphiles refer to amphiphiles that are constructed on the basis of noncovalent
interactions such as electrostatic interaction, π−π stacking, charge-transfer interaction,
hydrogen bonding, and host−guest interaction. Some dynamic and reversible covalent bonds
such as imine and disulfide bonds, which are similar to noncovalent interactions under certain
conditions, can also be used in the formation of supra-amphiphiles.
 There are two main strategies for fabricating supra-amphiphiles according to the structure
of the building blocks. One is to ‘create amphiphilicity' by the combination of the hydrophilic
part and the hydrophobic part through noncovalent interactions or dynamic covalent bonds.
And the other strategy is to ‘modulate amphiphilicity' by modifying conventional covalent
amphiphiles with the techniques of noncovalent synthesis.
 For amphiphilic species, topology dictates physical−chemical properties and applications.
So far, various topologies of supra-amphiphiles have been achieved, such as single-chain
head-to-tail, multi-chain head-to-tail and bola-form ones. Because of the convenience of
noncovalent synthesis, the fabrication of supra-amphiphiles with some specific topology can
be relatively less laborious and less difficult compared to that of their covalent counterparts.
 Due to the dynamic nature of noncovalent interactions and dynamic covalent bonds, the
supra-amphiphiles can be endowed with stimuli-responsiveness, changing the structures and
properties under certain circumstances, when the specific moieties which are sensitive to pH,
temperature, competitive components, light and enzymes etc. are introduced into the systems
by rational design. Therefore, it is anticipated that supra-amphiphiles can be capable
candidates in the areas of smart nanoscale carriers, chemical analysis, highly emissive smart
materials, supramolecular photosensitizers with enhanced antibacterial efficiency and so on.
