摘要
如同自然界中浓度可以对矿石、细胞等形貌进行调控,我们设计了基于配位相互作用主导的浓度响应的体系。苝四羧酸通过与金属离子配位,并借助配位作用和π-π两种弱相互作用竞争,在不同浓度下形成了不同尺寸的材料。低浓度大尺寸材料具有饱和配位的性质,排列规整,因此具有较高的导电能力;高浓度小尺寸材料具有不饱和配位的性质,排列相对不规整,空余的羧基可以吸附氨气等碱性气。希望该工作可以对浓度调控的自组装体系进行启示。~1
Inspired by the natural spontaneous adaptability to the environmental changes,we have designed a weak interaction predominated self-assembly system,which could adapt to the total concentration changes by adjusting coordination states autonomously.By thoroughly studied the microscopic building blocks at molecular level,we found out that saturated coordinating nano-belts had a more periodic molecular arrangements,thus causing a higher conductivity in application.And because of unoccupied carboxyl groups,the unsaturated coordinating micro-belts have higher surface area and more acidic sites to absorb NH_3 gas in application.We hope our attempt to explain the concentration dependent size control of self-assembling system could help us better understand the natural adaptability.
