We report a study of the behavior of four dynamic covalent libraries (DCLs) based on acylhydrazones and of the corresponding square constitutional dynamic networks (CDNs) under the effect of three agents, namely, metal cations, base + metal cations and light irradiation; in particular, the successful switching of the CDN between two orthogonal distributions results, respectively, from metallo-selection and photo-selection. The four DCLs undergo triple adaptation when subjected to the three agents with the generation of specific CDN distributions characteristic of each of the four DCLs. The ternary outputs displayed by the DCLs present three states (-1, 0 and 1) related to three different constitutional distributions expressed in response to the triple inputs applied. This latter process amounts to the storage of molecular information in dynamic distributions rather than in selective interactions between complementary entities undergoing molecular recognition.
我们报告了一项关于基于酰腙的四个动态共价库（DCL）以及相应的方形结构动态网络（CDN）在三种试剂作用下行为的研究，这三种试剂分别是金属阳离子、碱 + 金属阳离子和光照射；特别是，CDN在两种正交分布之间的成功切换分别源于金属选择和光选择。当四个DCL受到这三种试剂作用时会发生三重适配，生成四个DCL各自特有的特定CDN分布。DCL显示的三元输出呈现与响应所施加的三重输入而表达的三种不同结构分布相关的三种状态（-1、0和1）。后一过程相当于将分子信息存储在动态分布中，而非存储在经历分子识别的互补实体之间的选择性相互作用中。
