摘要/Abstract

摘要： 本文设计并合成了一种新型蒽衍生物蓝光材料2-叔丁基-9,10-二(9,9-二正丙基芴基)蒽.化合物中引入的柔性烷基链有效抑制了分子间的相互作用,使该化合物不易结晶,同时提高了化合物在有机溶剂中的溶解度.通过量子力学方法计算发现,化合物具有顺反两种稳定构型,分子的平面性差,能减弱分子间相互作用.化合物在二氯甲烷溶液中的最大荧光发射峰在443 nm,在环己烷溶液中测得荧光量子效率为0.78,固态薄膜的最大发射峰波长相对溶液有少量红移(450 nm).热失重和差热分析结果表明,该化合物具有较高的热稳定性,分解温度和玻璃化转变温度分别为365℃和126℃.

Abstract: A new soluble anthracene derivative 2-tert-butyl-9,10-bis (9,9-dipropylfluorenyl)anthracene was designed and synthesized.The compound has high solubility in common organic solvent and does not tend to form crystal due to introducing of the flexible alkyl groups.Through theoretical calculations we found that the compound has two stable conformations and the substituents are highly twisted,which can mitigate unfavorable steric interacton.The compound exhibits blue-light emission in dichloromethane solution (λ_max=443 nm) and solid state (λ_max=450 nm),the fluorescence quantum efficiency in cyclohexane solution is measured to be 0.78.TGA and DSC results show the compound has high thermal stabilities,the decomposition temperature and glass transition temperature are 365℃ and 126℃ respectively.

Key words: blue-light emitting material, anthracene derivative, theoretical calculations, thermal stability
