摘　　要：以N ,N -二乙基间氨基苯酚 ,对羧基苯甲醛为原料 ,合成了两种新的罗丹明衍生物 ,这种合成方法获得的产物单一 ,避免了在罗丹明染料通常的合成工艺中产生 5 ,和 6 ,位异构体混合产物 ,减少了繁琐的分离纯化工序 ,降低了制备成本 ,该合成方法操作简便 ,产率优良 (总收率≥ 90 % )。Two novel kinds of Rhodamine derivatives were synthesized with 3-diethylaminophenol and 4-carboxybenzaldehyde as raw materials. The product of the synthesis method was sole, avoiding the production of 5, and 6, isomers mixture in the normal synthesis processes of Rhodamine dyes, so that the burdensome processes of separation and purification were greatly reduced, and the cost of production was saved. The synthesis of the two Rhodamine derivatives was convenient and the yield was satisfactory (≥90 %).
