A short peptide based hydrogel exhibits aqueous insolubility, thixotropy and efficient light induced syneresis. Upon irradiation with UV light, the hydrogel shrinks and expells ~50% of the solvent. Syneresis is caused by light-triggered trans-cis isomerisation of an azobenzene moiety in the peptide derivative. This expulsion of solvent can be effectively exploited in the removal of low molecular weight contaminants in water.

, (2016/10/10)
PROBLEM TO BE SOLVED: To provide an azobenzene compound capable of repeated structural changes without heating, and a heat pump system using the same. SOLUTION: An azobenzene compound represented by the general formula (1) and undergoing cis-trans isomerization reaction upon light irradiation is used as a heat medium of a heat pump system. In the formula, at least one of R1 to R3 is (CH2CH2O)n-R10; R4 is R11, O-R11, NH-R11, or COO-R11; X- is Cl-, Br-, I-, BF4-, PF6-, CH3(CH2)nSO3-, TsO-, (YSO2)2 N-, or (NC)2 N-; n is an integer between 0 and 2; and Y is F, CF3, or C2F5.

PROBLEM TO BE SOLVED: To provide an azobenzene compound capable of changing a structure repeatedly without heating and a heat pump system using it. SOLUTION: An azobenzene compound expressed by the formula (1) and reacts by cis-trans isomerization by light radiation, is used as a heat medium of a heat pump system. The azobenzene compound expressed by the formula (1) is subjected to endotherm by melting latent heat when phase change from a solid phase trans body to a liquid phase cis body occurs, and is subjected to heat evolution when phase change from the liquid phase cis body to the solid phase trans body occurs.
