以傅克酰基化反应、串联的Aldol-Michael反应及Pd-催化的脱卤化氢环化反应为关键步骤,合成了低取代的二苯并并四苯衍生物(DBN).通过1H-NMR位移值随浓度改变而改变的方法测定了DBN在溶剂中的聚集效应,通过紫外吸收及荧光放射光谱的测定分析了DBN的发光性能.
Low-substituted dibenzotetracene derivatives (DBN) were synthesized by Friedel-Crafts reaction, Aldol-Michael reaction in series and Pd-catalyzed dehydrohalogenation reaction. By 1H-NMR The concentration of DBN in the solvent was measured by the method of changing the concentration. The luminescence properties of DBN were analyzed by UV absorption and fluorescence emission spectrometry.
