| 英文摘要 | Self-assembly is an efficient strategy of constructing microgel-based intelligent materials. However, it remains a challenge to realize the reversible self-assembly of microgels. Herein, a method to guide the self-assembly of soft colloids with light-stimuli is proposed, utilizing the light-responsive host-guest interaction between an azobenzene functionalized nanogel (the guest colloid) and an -cyclodextrin functionalized microgel (the host colloid). The two colloids can form a stable colloid cluster when the surface of the host colloid is fully packed with the guest colloids. The colloid cluster can disassemble when irradiated with UV light and reassemble when irradiated with visible light. The reversible colloidal self-assembly can be controlled by the interplay between the supramolecular and covalent crosslinking, and can also be adjusted by the addition of competitive host molecules. Besides the light-sensitivity, the colloid cluster inherits the deformability and temperature-sensitivity from its parent colloids. These features are different from the supramolecular self-assembly of hard colloids or macroscopic gels, and manifest the as-prepared colloid cluster potential building blocks of light-responsive materials. |
