巧妙的超分子组装技术是纳米材料研究的重要课题之一。本文以表面季铵化的阳离子碳量子点（CDots）为组装和荧光平台，阴离子磺酸基杯[4]芳烃为连接体，Tb3+离子原位配位，提出了一种精细的超分子组装策略，用于多功能纳米器件的制备。超分子相互作用的动态平衡特性最终可以赋予这种纳米器件荧光比率分子识别功能，并作为具有两个输出通道的纳米逻辑门。
Ingenious approaches to supramolecular assembly for fabricating smart nanodevices is one of the more significant topics in nanomaterials research. Herein, by using surface quaternized cationic carbon dots (CDots) as the assembly and fluorescence platform, anionic sulfonatocalix[4]arene with modifiable lower and upper rims as a connector, as well as in situ coordination of Tb3+ions, we propose an elaborate supramolecular assembly strategy for the facile fabrication of a multifunctional nanodevice. The dynamic equilibrium characteristics of the supramolecular interaction can eventually endow this nanodevice with functions of fluorescent ratiometric molecular recognition and as a nano‐logic gate with two output channels.
