中文摘要：
通过Heck偶联反应合成了3个新的长共轭结构芴类衍生物（3a-3c），其结构经^1H NMR，IR和元素分析表征。测定了3在THF溶液中电子吸收和光致发光性能。结果发现3呈现高的发光强度，D-π-D型化合物比A-π-A型化合物荧光发光强度高，对产生这一光谱行为的主要原因进行了分析。
英文摘要：
Three new fluorene derivatives with long or-electron conjugated structure （3a - 3c） were synthesized by the Heck coupling reaction. The structures were characterized by ^1H NMR, IR and elemental analysis. The optical property of 3 in THF was evaluated. The results showed that 3 possesses well luminescence property and the fluorene with donor - π - donor structure displays higher luminescence intensity than that with acceptor - π - acceptor structure. The major reasons of such behavior were discussed.
