Supramolecular strategy for smart windows.

Smart windows are a promising solution to improve energy-saving efficiency and indoor comfort due to their potential functionalities including solar modulation, coloration, self-cleaning, self-power, and moisture scavenging. Recently, smart windows constructed by a supramolecular strategy have attracted increasing attention due to the inherent dynamic, reversible and adaptive properties of noncovalent interactions, which can endow the fabricated smart windows with desired fascinating functionalities. In this review, emerging supramolecular strategy-based materials are outlined and their applications for fabricating smart windows are summarized. Mechanisms and properties of the functional supramolecular materials are demonstrated, especially their solar modulation ability and color change effect. Challenges and opportunities for the supramolecular strategy-based materials are also discussed for future innovation in the development of ideal smart windows.
