一种用于显示器材料的乙基环己基苯基烷基酮化合物及其制备方法
摘要：
本发明涉及一种用于显示器材料的乙基环己基苯基烷基酮化合物，结构式如式(一)所示：其中，R选自(CH2)3CH3或(CH2)2CH3。所述乙基环己基苯基烷基酮化合物的制备方法包括：1)乙酰环己基苯的合成；2)乙基环己基苯的合成；3)乙基环己基苯基烷基酮化合物的合成。所述的乙基环己基苯基烷基酮化合物中刚性核心含有烷酰基与苯基部分连接，羰基基团引入末端取代基的两种各向异性酮，与侧向取代的化合物相反，这些酮的清亮点高于相应的烃的清亮点，更适合在显示器中使用，而且制备方法简易，适合工业化生产。
摘要（英）：

The present invention relates to ethylcyclohexylphenylalkyl ketone compounds used for a display material. The compounds have a structural formula represented by a formula (I) shown in the description,wherein R is one selected from (CH2)3CH3 and (CH2)2CH3. The preparation method of the ethylcyclohexylphenylalkyl ketone compounds comprises the following steps: 1) synthesis of acetylcyclohexylbenzene; 2) synthesis of ethylcyclohexylbenzene; 3) synthesis of the ethylcyclohexylphenylalkyl ketone compounds. The rigid core of the ethylcyclohexylphenylalkyl ketone compounds provided by the inventioncontains alkanoyl linked with a phenyl part, two anisotropic ketones with terminal substituent groups are introduced into carbonyl, as opposed to a laterally-substituted compound, clearing points of the ketones are higher than a clearing point of one corresponding hydrocarbon, so that the compounds are more suitable for use in displays; and the preparation method is simple and easy, and suitable for industrial production.
