[E-(1)A(1)C, (1)A(2)C, (2)A(1)C, (2)A(2)C] undergoes photoselection by irradiation of the system, which causes photoisomerization of E-(1)A(1)C into Z-(1)A(1)C with amplification of the latter. The set of acyl hydrazones [E-(1)A(1)C, (1)A(3)C, (2)A(1)C, (2)A(3)C] undergoes a dual adaptation via component exchange and selection in response to two orthogonal external agents: a chemical effector, metal cations
腙 (a)A(b)B 和酰基腙 (a)A(c)C 的结构动态库会响应化学效应物(金属阳离子)或物理刺激(光)而发生重组和适应。腙组 [(1)A(1)B, (1)A(2)B, (2)A(1)B, (2)A(2)B] 在添加锌阳离子时进行金属选择通过选择最适合的组件 (1)A(2)B 放大 Zn((1)A(2)B)2。一组酰基腙 [E-(1)A(1)C, (1)A(2)C, (2)A(1)C, (2)A(2)C] 通过系统的辐照进行光选择,这导致 E-(1)A(1)C 光异构化为 Z-(1)A(1)C,后者放大。一组酰基腙 [E-(1)A(1)C, (1)A(3)C, (2)A(1)C, (2)A(3)C] 通过组分经历双重适应响应两个正交外部因素的交换和选择:化学效应物,金属阳离子,和物理刺激,光照射。金属选择发生在锌阳离子的添加上,锌阳离子通过选择最适成分 (1)A(3)C 来驱动 Zn((1)A(3)C)2
