A cyclodextrin aldehyde based molecularly imprinted polymer with thermally responsive Diels–Alder (DA) linkages of grafted furan-type dienes was polymerized. The synthesized DA-MIP has dienophile characteristics and the specific absorption of ethyl carbamate (EC) can be switched on or off simply by thermal adjustment to 130 °C and 60 °C, respectively. The imprinting factors (α) of the MIP and rDA-MIP to EC were 6.2 and 5.0, and the selection factors (β) were 5.2 and 4.0, respectively. The restoration of the molecular target ratio was 88%, as determined by absorption and desorption experiments. The thermal restoration ratio, determined by thermal cycling experiments, was 78%. A new electrochemical sensor was prepared using the DA-MIP and its responsiveness for detecting trace amounts of EC was investigated. The results indicate that the electrode response has good affinity and excellent specific recognition performance for template molecular chemicals.

选择性吸附氨基甲酸乙酯的可切换智能分子印迹聚合物的合成及其在电化学传感器分析中的应用†
聚合了具有接枝呋喃型二烯的热响应 Diels-Alder (DA) 键的基于环糊精醛的分子印迹聚合物。合成的 DA-MIP 具有亲双烯体特性，氨基甲酸乙酯 (EC) 的比吸收可以分别通过热调节至 130°C 和 60°C 来打开或关闭。MIP和rDA-MIP对EC的印记因子（α）分别为6.2和5.0，选择因子（β) 分别为 5.2 和 4.0。通过吸收和解吸实验确定，分子目标比率的恢复为88%。通过热循环实验确定的热恢复率为78%。使用 DA-MIP 制备了一种新的电化学传感器，并研究了其检测痕量 EC 的响应性。结果表明，该电极响应对模板分子化学品具有良好的亲和力和优异的特异性识别性能。
