negative photochromic compounds, donor-acceptor Stenhouse adducts (DASAs), is reported. Tailoring the electron deficient "acceptor" moiety yielded DASAs that can be activated with mild visible and far red light. The effect of acceptor composition on reactivity, absorption, equilibrium, and cyclability is exploited for the design of high performance photoswitches. The structural changes to the carbon acid
报道了一种新型可调负光致变色化合物库,供体-受体 Stenhouse 加合物 (DASA)。定制缺电子的“受体”部分产生了可以用温和的可见光和远红光激活的 DASA。受体组成对反应性、吸收、平衡和循环性的影响被用于设计高性能光开关。通过促进与缺电子胺供体的开环反应,碳酸受体的结构变化还提供了获得新的、结构更加多样化的 DASA 衍生物的途径。
