“…By comparing to other stimuli (chemical inputs [3] , pH [4][5] , and temperature [6][7][8] ), use of light source is thought to be elegant as of its nondestructive nature and controllable spatiotemporal resolution. Such photoresponsive systems have been well-programmed for the application of transmembrane transport [9][10][11] , gel materials [12] , catalysis [13] and other fields [14] . Among commonly utilized photoswitches, azobenzene is one of the most widely studied groups in the design of photoresponsive supramolecular systems due to its feasible synthetic method and reversible photoisomerization quantum yield [15] .…”

Given the nondestructive nature and high spatiotemporal resolution of the light source, studies of photoresponsive systems have gained great attention and made considerable progresses in the past decades. By incoporationg photoswitch molecules with noncovalent interaction, photoresoive, supramolecular systems can be designed for tailored properties, e.g., guest delivery, catalysis, sensing, and information processing. Here, we introduced a new photoresponsive ligand (L) comprised of azobenzene spacer and two tris(urea) binding moiety. The latter component displayed characteristic coordination property with anions. Upon light irradiation, we observed reversible photoswitching of free ligand. The Z/E thermal relaxation half-life of free ligand L was determined to be 3.4 h at room temperature. By coordinating to phosphate anion, double helicate structure was believed to form and can be subsequently regulated by light and heat.
