substrate modification. A small library of cycloadducts suitable for the above applications was prepared, and the temperature dependence of the retro-Diels–Alder processes was determined through in situ1H NMR analyses complemented by computational calculations. The practical range of the reported systems ranges from 40 to >110 °C. The cycloreversion reactions are more complex than would be expected based
呋喃与马来酰亚胺之间的反应已越来越成为一种令人感兴趣的方法,因为它的可逆性使其成为自修复材料,自毁聚合物,细胞培养用水凝胶和骨修复制剂等应用的有用工具。然而,这些应用中的大多数都依赖于简单的单取代呋喃和简单的马来酰亚胺,并且还没有广泛评估通过简单的底物修饰可实现的固有的潜在热变异性。准备了一个适合上述应用的小型环加合物库,并通过原位1确定了Diels-Alder逆过程的温度依赖性。1 H NMR分析辅以计算计算。所报道的系统的实际温度范围为40至> 110°C。环还原反应比基于材料前沿分子轨道分析所预期的简单趋势所预期的复杂得多。
