利用核磁共振研究可逆热变色物质的变化机理

STUDY ON THE THERMOCHROMIC MECHANISM OF REVERSIBLE THERMOCHROMIC MATERIALS WITH NMR

利用核磁共振光谱研究了可逆热变色复配物的变色机理．结果表明：变色色基在酸性条件下开环，形成共轭结构；双酚Ａ在高温时不解离。

Based on the identification of NMR spectra the thermochromic mechanism of reversible thermochromic composite materials has been investigated.The investigated results indicated that the ring opening of the molecule of colorant occurred and the conjugated structure formed under the acidic conditions.There was no dissociation of Bisphenol A at elevated temperatures.Bisphenol A can be dissociated under the basic condition.
