We report on dual, light-responsive and redox-active foldamers that demonstrate reversible and robust stimuli-induced behaviour. Herein, UV/Vis, H NMR and circular dichroism (CD) spectroscopy and cyclic voltammetry have been used to establish the reversibility and highly robust nature of the light- and redox-driven behaviour of these new foldamers with minimal levels of fatigue observed even upon multiple cyclic treatments with irradiative/non-irradiative and oxidative/reductive conditions. This proof-of-concept work paves the way towards the creation of novel stimuli-responsive foldamers of increasing sophistication capable of demonstrating reversible and robust responses to multiple distinct stimuli.
我们报道了具有光响应和氧化还原活性的双功能折叠体,它们表现出可逆且强大的刺激诱导行为。在此,紫外可见光谱、核磁共振氢谱、圆二色光谱和循环伏安法已被用于确定这些新型折叠体在光驱动和氧化还原驱动行为方面的可逆性和高度稳定性,即使在辐射/非辐射以及氧化/还原条件下进行多次循环处理,观察到的疲劳程度也极低。这项概念验证工作为创造越来越复杂的新型刺激响应折叠体铺平了道路,这些折叠体能够对多种不同刺激表现出可逆且强大的响应。
