Transparent-to-black full-visible high-contrast switching from an engineered dual electro-thermoresponsive single-molecule towards effective solar light control |
| 초록 |
This study presents an alternative approach to achieve transmissive-to-black chromism by dual stimulation of a new responsive molecule where an asymmetric viologen is integrated onto a newly engineered poly(2-isopropyl-2-oxazoline)-based molecule. The synergistic effect of its thermochromic and electrochromic response shows full absorption of the entire visible solar spectrum that is ideal for building facades requiring absolute privacy. Autonomous chromic switchability function is also possible by independently stimulating the material either electrically or thermally where it displays unique colored state of vibrant magenta and a hazy state, respectively. Tunability of the overall performance in terms of optical contrast, switching kinetics, coloration efficiency and cyclic stability based on the lattice water concentration is also exhibited by the new material. |
