Single-crystal supramolecular organic framework with super-adaptation

具有超适应性的超分子有机骨架单晶

Nature is unrivaled in its ability to create sophisticated architectures via hierarchical,precisely organized and ordered assembly of simple structural motifs[1].Adaptation is ubiquitous in living systems,inducing evolution toward more sophisticated architectures with atomic precision,which usually involve superadaptive changes of structure and function to maintain the normal operation of life systems[2,3].For instance,the super-adaptive transition of DNA from original structure to the nucleosome,superhelix or chromatin structure makes the volume shrinkage of 86%-99.9%,which is the key process to regulate DNA functions[4].Inspired by these delicate processes,scientists have devoted enormous efforts to mimicking the natural assembly process for developing advanced functional materials[5-7].
