<p>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 Rto Ris (CHCHO)n-R; Ris R, O-R, NH-R, or COO-R; Xis Cl, Br, I, BF, PF, CH(CH)nSO, TsO, (YSO)N, or (NC)N; n is an integer between 0 and 2; and Y is F, CF, or CF.</p> |
