Structure and Ion-Selective Properties of 2-Phosphorylphenols
摘要:
The structure and ion-selective properties of some 2-phosphorylphenols were studied. It was shown that, irrespective of the nature of the substituents on the benzene ring and on the phosphorus atom, these compounds exhibit potentiometric selectivity to cesium cation. The crystal structures of 2-(diphenylphosphoryl)-4-ethylphenol and 2-[(diphenylphosphoryl)methyl]phenol were established.

significantly exceeds stability constant of Ga3+ complex with 8 (logKGaL = 26.63 ± 0.24). Ligands 8 and 9 are as effective for Ga3+ cation binding as ethylenediamine-N,N’-diacetic-N,N’-bis(methy1enephosphonic) acid and ethylenediamine-N,N,N’,N’-tetrakis(methylenephosphonic) acid, respectively. The labelling process and stability of [68Ga]Ga-8 and [68Ga]Ga-9 were studied. Both 8 and 9 readily form 68Ga-complexes
