exchangeable dynamic covalent bonds that can be triggered by readily usable stimuli offer easy incorporation of their dynamic properties in various molecular systems, but the library of such bonds is still being developed. Herein, we report the dynamic covalent chemistry of 2,2,6,6‐tetramethylpiperidine‐1‐sulfanyl (TEMPS) dimers derived from thermally reversible homolytic dissociation of disulfide linkages
可以由易于使用的刺激触发的内在可交换动态共价键可以轻松地将其动态特性整合到各种分子系统中,但是此类键的库仍在开发中。在这里,我们报道了由二硫键的热可逆均相分解产生的2,2,6,6-四甲基哌啶-1-硫烷基(TEMPS)二聚体的动态共价化学。即使在100°C时,TEMPS仍具有很高的空气稳定性,从而在大气条件下易于进行热解离-缔合平衡和可调节的键交换性质。我们还为二聚体的可修饰衍生物建立了一条有效的合成路线,该路线能够将动态特性并入线性和网络聚合物结构中。
