1,7-Diaza-12-crown-4 can be used to prepare:
- A ligand named N,N′-bis[(6-carboxy-2-pyridyl)methyl]-1,7-diaza-12-crown-4, which is used to synthesize lanthanide metal complexes applicable as MRI contrast agents.
- A novel chiral receptor that can be used in the separation of enantiomers using capillary electrophoresis.
- A fluorescent anthracene based diazacrown ether, which can be used as a photoinduced electron transfer (PET) fluorescent sensor for guest cations.
| [Synthesis]
Preparation of azacrown ether: the bromine salt of compound 1,7-dioxa-4,10-tetraaza (2.6 g, 5.39 mmol) and phenol (3.04 g, 32.32 mmol) were added to 150 mL of 33% hydrogen bromide acetic acid solution. The reaction was warmed up to reflux at 80 °C and sti |
