合理的设计来控制晶体固体中分子转子的动力学是很有意义的，因为它提供了具有精确可调功能的先进材料。在这里，我们描述了用固溶体方法控制柔性多孔性配位聚合物(PCP)中转子的旋转频率。柔性PCPS的固溶体[{Zn(5-nitroisophthalate)(x)(5-methoxyisophthalate)(1-x)(deuterated(4，4‘-联吡啶)(DMF-MeOH)](N)允许通过改变固溶体比x来连续调节晶胞体积。异构体的变化提供了分子转子(4，4’-联吡啶基环)周围的局部环境的连续变化，导致旋转频率的控制而不需要改变温度。
Rational design to control the dynamics of molecular rotors in crystalline solids is of interest because it offers advanced materials with precisely tuned functionality. Herein, we describe the control of the rotational frequency of rotors in flexible porous coordination polymers (PCPs) using a solid-solution approach. Solid-solutions of the flexible PCPs [{Zn(5-nitroisophthalate)(x)(5-methoxyisophthalate)(1-x)(deuterated 4,4'-bipyridyl)}(DMF-MeOH)](n) allow continuous modulation of cell volume by changing the solid-solution ratio x. Variation of the isostructures provides continuous changes in the local environment around the molecular rotors (pyridyl rings of the 4,4'-bipyridyl group), leading to the control of the rotational frequency without the need to vary the temperature.
