Driving Forces for the Formation of Supra-
Amphiphile
The driving force for the formation of supra-amphiphile differs. As
shown in Fig. 6.2, the driving force could be one single noncovalent
interaction, such as hydrogen bonding [6,7], host-guest interaction
[8,9] coordination bond [10,11], electrostatic interaction [12-14],
charge transfer interaction [15,16], and hence forth. The driving
force can also be the combined interaction of different forces. For
example, the combined interaction of electrostatic and charge
transfer can be used for the construction of supra-amphiphiles,
which generate ultra-long nanofibers in aqueous solution [17].

(a) hydrogen bonding, (b) host-guest interaction, (c)
coordination bond, (d) electrostatic interaction, (e) charge
transfer interaction, and (f ) the combined interaction of
electrostatic and charge transfer.
Owing to its dynamic and reversible nature, dynamic covalent
bond (DCB) is in many ways much like noncovalent interactions
[18-23]. Therefore, it can also be used as a driving force for the
