Amphiphilic self-assemblies arising from orthogonally switchable block copolymers are promising candidate in drug delivery, due to their structure and transformation diversity, which is superior to the presently most studied singly responsive copolymers [1]. To induce this process completely non-invasively, light in combination with temperature is utilized as the stimulus. Introduction of suitable photoactive functional groups could modulate the LCST of the copolymer, thereby achieving the stage that all aggregate scenarios could be concluded in a certain temperature range. For characterization of the copolymer structure, measurements are implemented by dynamic light scattering (DLS), small angle X-ray scattering (SAXS) and -neutron scattering (SANS), while the phase behavior as well as phase transition kinetics are investigated by the time-resolved scattering methods.
