Thermal responsive polydiacetylene derived from PAMAM dendrimer (PDA-G₀) was synthesized. Unlike the ethylenediamine substituted PDA (PDA-NH₂) solution, the prepared PDA-G₀ vesicle solution showed reversible thermochromism property when temperature varied from 20 to 90 °C, which is due to the formation of an internal hydrogen bond in amide groups. Furthermore, PDA-G₀/PMMA film with excellent stability was obtained by a mixed-drying method, which could be stored for a long time without denaturation. After polymerization by UV irradiation, it displayed much better reversible thermochromic ability and the responded temperature range became wider, from 20 to 110 °C.

在水溶液和固体膜中具有良好的可逆热致变色能力的新型树枝状聚二乙炔传感器

合成了衍生自PAMAM树枝状聚合物（PDA-G ₀）的热响应性聚二乙炔。不同于乙二胺取代的PDA（PDA-NH ₂）溶液，当温度在20至90°C之间变化时，制得的PDA-G ₀囊泡溶液表现出可逆的热致变色特性，这是由于在酰胺基团中形成了内部氢键。此外，通过混合干燥法获得了稳定性优异的PDA-G ₀ / PMMA膜，该膜可以长时间保存而不会变性。通过紫外线照射聚合后，它表现出更好的可逆热致变色能力，响应温度范围从20到110°C变宽。
