complex actuated assembly can induce the extension of -conjugation in a supramolecular way, which leads
to the redshift of absorption spectrum and, therefore, enhanced photothermal conversion efficiency in NIR
biowindow. For nanomaterials, their photothermal conversion efficiency is closely related to size or
supramolecular arrangement. Therefore, through the host-guest interaction-induced size or supramolecular
arrangement, their photothermal performance can be flexibly manipulated.
