摘　　要：通过芴和芳香醛在相转移催化剂三乙基苄基氯化铵存在下发生缩合反应,合成了12个标题化合物,测定了前7个化合物在17种溶剂中的紫外光谱,在极性和非极性溶剂中,其紫外光谱的最大吸收峰频率与Hammett亲电取代常数之间呈良好的线性关系。Twelve diphenylfulvenes were synthesized by the condensation of fluorene with aromatic aldehydes in alkaline solution in the presence of phase transfer catalysis (PTC). The UV Spectra of compounds 1-7 in seventeen solvents have been measured. A linear relationship between vmaxUV and |σp+| is obtained.
