A polar homochiral 3D MOF [{Co2(L)(bpe)(H2O)}·5H2O]n constructed with cobalt(II) and a new ligand N-(1,3-dicarboxy-5-benzyl)-carboxymethylglycine (H4L) accommodates ordered helical water streams in its helical grooves. It provides the first example of switchable ferroelectric and optical behavior through two-step reversible single-crystal to single-crystal transformation (SCSC) upon desorption/adsorption of water spirals and coordinated water molecules, respectively.
一个由钴(II)和一个新的配体 N-(1,3-二羧基-5-苄基)-羧甲基甘氨酸 (H4L) 构建的具有手性的极性 3D MOF [{Co2(L)(bpe)(H2O)}·5H2O]n 可以在其螺旋槽中容纳有序的螺旋水分子。它通过水螺旋和配位水分子的吸附/解吸，分别提供了通过两步可逆的单晶到单晶转变 (SCSC) 来实现铁电和光学性能可切换的首例例子。
