A poly[(2-ethyl-2-oxazoline)-ran-(2-nonyl-2-oxazoline)] copolymer in combination with hydroxypropylated cyclodextrins has been demonstrated to lead to a supramolecular self-assembly process that results in the formation of kinetically trapped thermoresponsive nanoparticles. Selection of the cyclodextrin type provides control over the nanoparticle phase-transition thermodynamics, thus affording optical temperature sensors with an unprecedented, long-term thermal memory function, which is reversible or irreversible. This research also sheds light onto kinetic and dynamic supramolecular assemblies, thus providing important insight because similar supramolecular processes are at the foundation of living matter.
已证明，聚[（2-乙基-2-恶唑啉）-无规-（2-壬基-2-恶唑啉）]共聚物与羟丙基化环糊精相结合会引发超分子自组装过程，从而形成动力学捕获的热响应性纳米颗粒。环糊精类型的选择可控制纳米颗粒的相变热力学，从而提供具有前所未有的长期热记忆功能的光学温度传感器，该功能可以是可逆的或不可逆的。这项研究还揭示了动力学和动态超分子组装，从而提供了重要的见解，因为类似的超分子过程是生命物质的基础。
