Direct synthetic routes to functionalised crown ethers. [PDF]
Org Chem Front, 2021 Crown ethers are macrocyclic hosts that can complex a wide range of inorganic and organic cations as well as neutral guest species. Their widespread utilization in several areas of fundamental and applied chemistry strongly relies on strategies for their

LCST phase behavior of benzo-21-crown-7 with different alkyl chains
Beilstein Journal of Organic Chemistry, 2019 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.

New crown-ether Dibenzo-18-crown-4 ligand via sequential one-pot reaction
Results in Chemistry, 2021 A friendly synthetic rout for a new crown-ether was developed in this short communication. The method in question was able to produce the desirable product in high yields (up to 80%), even after some purification steps.
