Abstract

The introduction of hydrophobic units into crown ethers can dramatically decrease the critical transition temperature of LCST and realize macroscopic phase separation at low to moderate temperature and concentration. Minor modifications in the chemical structure of crown ethers (benzo-21-crown-7, B21C7s) can effectively control the thermo-responsive properties.

摘要

将疏水单元引入冠醚中可显著降低低临界溶液温度（LCST）的临界转变温度，并在低温至中温及浓度条件下实现宏观相分离。对冠醚（苯并 - 21 - 冠 - 7，B21C7s）化学结构进行微小修饰可有效控制其热响应特性。
