The novel Yb succinate metal–organic framework exhibits a reversible single‐crystal to single‐crystal polymorphic transformation (see figure) when it is heated above 130 °C, returning to its initial form when back at room temperature. This transformation produces a change in the coordination sphere of the Yb atoms, which influences the catalytic activity of the material.
新颖的Yb琥珀酸金属-有机骨架在130°C以上加热时,表现出可逆的单晶至单晶多晶型转变(见图),在室温下恢复为初始形式。这种转变在Yb原子的配位范围内产生变化,从而影响了材料的催化活性。
