Two nonporous coordination polymers were found to possess large anisotropic thermal expansion, which was derived from the flexible structures. A "spring-like" thermal motion was proposed to illustrate the mechanism. Compound Cd(eim) (eim = 2-ethylimidazole) possesses large linear and reversible thermal expansion properties and the emission intensity shows a linear decrease with temperature, making it a candidate for thermo-responsive materials.
发现两种无孔配位聚合物具有较大的各向异性热膨胀，这源于其柔性结构。提出了一种“弹簧状”热运动来解释其机理。化合物Cd(eim)（eim = 2-乙基咪唑）具有较大的线性和可逆热膨胀特性，且发射强度随温度呈线性下降，使其成为热响应材料的候选物。
