合成了具有ALE活性的2-methoxy-6-[[[4-(1，2，2-triphenylvinyl)phenyl]亚氨基]-甲基]苯酚配体(HTPEIPOMe)的双功能镝二聚体[Dy-2(HTPEIPOMe)(2)(OAc)(4)(NO3)(2)](1)。它不仅表现为零场下势垒为168(15)K的单分子磁体(SMM)，而且在压制发烟循环中表现出可切换的颜色、光致发光和磁响应的压致变色。
A bifunctional dysprosium(III) dimer, [Dy-2(HTPEIPOMe)(2)(OAc)(4)(NO3)(2)] (1), comprising an ALE-active (AIE = aggregation-induced emission) ligand of 2-methoxy-6-[[[4-(1,2,2-triphenylvinyl)phenyl] imino] - methyl]phenol (HTPEIPOMe), was successfully synthesized. It not only behaves as a single-molecule magnet (SMM) with an energy barrier of 168(15) K at zero field but also exhibits piezochromism during the pressing fuming cycle with switchable color, photoluminescence, and magnetic response.
