substitutions alter the pH range in which rapid interconversion occurs. Herein, more impactful structural modifications were performed via alteration of the characteristic phenyl rings to alternative aromatic systems. It was determined that the scaffold was still viable after these changes and that the range of accessible midpoint pH values was markedly increased. To further explore the switch’s scope, scaffolds
以前对邻羟基查耳酮/黄酮酮分子转换支架的研究表明,简单的取代改变了发生快速相互转化的pH范围。本文中,通过将特征性苯环改变为替代的芳族体系进行了更具影响力的结构修饰。确定在这些改变之后,支架仍然是可行的,并且可达到的中点pH值的范围显着增加。为了进一步探索开关的范围,还研究了能够发生多个开关事件的支架。
