摘要

研究发现，N-壬基吩噻嗪自由基阳离子的磁性能随其反离子的不同而变化。NTf2-（双（N-三氟甲磺酰基）亚胺离子）、OTf-（三氟甲磺酸盐）和 BF4-盐中的自由基阳离子形成π-二聚体，具有很强的反铁磁相互作用。SbF6- 盐表现出顺磁性，但反铁磁作用很弱。有趣的是，当加热到 78 oC 时，NTf2- 盐转变为顺磁液态。

Magnetic Properties of N-Nonylphenothiazine Radical Cations Depending on Counter Anions

Magnetic properties of N-nonylphenothiazine radical cations were found to vary depending on their counter ions. The radical cations in NTf2– (bis(N-trifluoromethanesulfonyl)imide ion), OTf– (trifluoromethanesulfonate), and BF4– salts formed π-dimer with strong antiferromagnetic interactions. The SbF6– salt exhibited paramagnetic properties with quite weak antiferromagnetic interaction. Interestingly, the NTf2– salt transformed to the paramagnetic liquid state upon heating to 78 oC.
