loop that relies on the coordination-coupled deprotonation (CCD) of a hydrazone switch has been developed. Above a particular threshold of zinc(II), CCD releases enough protons to the environment to trigger a cascade of reactions that yield an imine. This imine sequesters the excess of zinc(II) from the hydrazone switch, hence lowering the effective amount of protons, and switching the cascade reactions
已经开发出依赖于腙开关的配位耦合去质子化 (CCD) 的负反馈回路。超过特定的锌 (II) 阈值,CCD 会向环境释放足够的质子,以触发产生亚胺的级联反应。这种亚胺从腙开关中隔离了过量的锌 (II),从而降低了质子的有效量,并将级联反应“关闭”,从而建立了负反馈回路。
