低取代二苯并并四苯的合成及性能研究(英文)
Synthesis and Character of Low Substituted Dibenzo [fg,op] Naphthacenes
【摘要】 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.
【Abstract】 Low substituted dibenzo [fg,op] naphthacenes were synthesized by using Friedel-Crafts acylation,tadem aldol-Michael solvent-free reaction and palladium catalyzed dehydrohalogenation cyclization as key steps.Their aggregation effect in solvent and emitting character are measured on the analysis of concentration dependent1H-NMR data and UV-vis,PL spectra respectively.
