4,13-Diaza-18-crown-6 (synonym Kryptofix 22) is a macrocyclic polyether ligand typically used as phase transfer catalyst (PTC) to bind cations in complex form.
A new highly sensitive and selective fluorescence chemosensor for Cr3+ based on rhodamine B and a 4,13-diaza-18-crown 6-ether conjugate. [1]
Thermodynamic study of complexation reactions between 1,7,10,16 Tetra oxa 4,13 diaza cyclo octa decane (Kryptofix22) and Ni2+, Cd2+ and Ag+ metal cations in some pure and binary mixed non-aqueous solvents using conductometry. [2]
Comparison of catalytic activities of new La(III) and Ce(III) complexes with different diaza-crown ether ligands for DNA hydrolytic cleavage. [3]
