This article presents a brief overview of recent advances in azo-containing supramolecular systems. In literature
it has been shown that azo supramolecular polymers and their composite materials exhibit fast and intelligent responses to various external stimuli
such as temperature
pH change
redox reagents
ligands
coupling reagents
etc
. In applications
these systems are widely used for molecular motors
shape memory
liquid crystal
solar thermal energy storage
signal transmission
intelligent encryption
and other purposes. Furthermore
these systems can function as key components for device upgrade processing. However
the design and rules of azo supramolecular polymers are still not supported by an exact theory. Information about the relationship between the spatial structure and behavior is lacking
and new supramolecular materials cannot be designed by adding functional moieties to known azo polymers. Based on the current research status
this review mainly summarizes the structural design principles as well as structures and applications of known azo supramolecules; meanwhile
it highlights the emerging development fields
recent advances
and prospects in fabricating self-assembling intelligent supramolecular systems with azo supramolecular polymers as responsive units. The goal of this review is to bring new inspiration to researchers who want to optimize the chemical structure
steric conformation
electrostatic environment
and specific molecular functionalization.
