We report a study of the behavior of four dynamic covalent libraries (DCLs) based on acylhydrazones ^aA^bB and of the corresponding square constitutional dynamic networks (CDNs) NA–ND under the effect of three agents, namely, metal cations, base + metal cations and light irradiation; in particular, the successful switching of the CDN NB 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.

酰腙的构成分布中构成动态网络和信息存储的多重适应†

我们报告了一项基于酰腙^a A ^b B的四个动态共价库 (DCL)和相应的方形构成动态网络 (CDN) NA–ND在三种试剂（即金属阳离子、碱+）作用下的行为研究。金属阳离子和光照射；特别是，CDN NB在两个正交分布之间的成功切换分别是金属选择和光选择的结果。当受到三种代理的影响时，四个 DCL 经历三重适应，并生成四个 DCL 中每个 DCL 的特定 CDN 分布特征。DCL 显示的三元输出呈现与响应所应用的三重输入而表达的三种不同构成分布相关的三种状态（-1、0 和 1）。后一个过程相当于以动态分布的形式存储分子信息，而不是在经历分子识别的互补实体之间选择性相互作用。
