TEMPERATURE PROGRAMMABLE SMALL MOLECULES FOR THERMORESPONSIVE SMART WINDOWS AND APPLICATIONS THEREOF

The present invention relates to design and applications of a class of water-soluble small molecules represented by formula 1. The said molecules, in their dilute aqueous solutions, exhibit lower critical solution temperature (LCST) phase transitions near room temperature, inducing a temperature triggered switching of opacity. Further, the present invention discloses a scalable smart window, akin to a radiative energy management system that can be incorporated into the built environment for imparting energy efficiency. The window fabrication is facile wherein the aqueous solution is sandwiched between two transparent glass panes to enable modulation of light and heat transmission. The dynamic window of present invention represents with multifarious applications in developing scalable, smart energy management systems for indoor building environments is envisioned to be a major contribution towards cost effective smart glass technologies.
