In 2022,Komaba, Kyoka; Nimori, Shigeki; Miyashita, Ryo; Kumai, Reiji; Goto, Hiromasa published an article in Polymer-Plastics Technology and Materials. The title of the article was 《Hydroxypropyl cellulose/poly(aniline-co-pyridine-oxyl) as a liquid crystal polymer/polyradical blend with helical magnetic structure》.Computed Properties of C5H7N3 The author mentioned the following in the article:
A helical magnetic polymer was synthesized by blending a polyradical and hydroxypropyl cellulose (HPC), which is a helical liquid crystal. First, achiral m-linked poly(aniline-co-pyridine) was synthesized via Buchwald-Hartwig coupling, and poly(aniline-co-pyridine-oxyl) as a linear polyradical was then prepared by Tokumaru method. Helicity was induced in the linear polyradical simply by blending with HPC as a helical cholesteric liquid crystal. The magnetic properties of the polyradical and the HPC/polyradical blend composite were evaluated by performing ESR, superconducting quantum interference device, and vibrating sample magnetometer measurements, which revealed that the linear polyradical shows diamagnetism up to 5 K and the polymer bend exhibits weak diamagnetism at high temperature and paramagnetism at low temperature2,6-Diaminopyridine(cas: 141-86-6Computed Properties of C5H7N3) was used in this study.
2,6-Diaminopyridine(cas: 141-86-6) belongs to pyridine. Pyridine and its simple derivatives are stable and relatively unreactive liquids, with strong penetrating odours that are unpleasant.Computed Properties of C5H7N3
