Abstract

Magnetoactive polymers based on 1,1′-binaphthyl-2,2′-diamine with axial chirality were synthesized through cross-coupling polycondensation of the Buchwald–Hartwig reaction and subsequent oxidation with m-chloroperoxybenzoic acid. The polymers were characterized with optical spectroscopy, electron spin resonance, superconducting quantum interference device, and synchrotron X-ray diffraction. Circular dichroism measurements revealed that the polymers exhibited optical activity. Magnetic measurements further showed that the polymers are organic chiral materials with weak antiferromagnetism owing to the presence of solid oxygen with low-dimensional ordering.

联萘苯胺基手性磁性聚合物

通过Buchwald-Hartwig反应的交叉偶联缩聚和间氯过氧苯甲酸的氧化反应，合成了具有轴向手性的1,1′-联萘-2,2′-二胺类磁活性聚合物。利用光谱学、电子自旋共振、超导量子干涉装置和同步加速器x射线衍射对聚合物进行了表征。圆二色性测量显示聚合物具有光学活性。磁性测量进一步表明，聚合物是有机手性材料，由于存在低维有序的固体氧，具有弱反铁磁性。
