摘　　要：以醛、酮为原料经羟醛缩合反应合成了具有一类含查尔酮结构的光敏性二胺:1-(3-氨基苯基)-3-(4-氨基苯基)-2-丙烯-1-酮与对-二(间氨基肉桂酰)苯。通过优化实验得到最佳的合成工艺为:醛、酮在温度为0℃下,以乙醇为溶剂,氢氧化钠为催化剂,进行羟醛缩合反应3h。收率可达到86%,经液相色谱分析其纯度分别为99.92%,99.91%,紫外可见最大吸收波长分别为349nm、361nm。所得方法操作简便,收率较高,原料易得。并用元素分析、核磁共振、红外光谱等手段对产物的结构进行了表征。A serial of photosensitive terials aldehyde and ketone through diamines containing chalcone moiety was prepared using the mathe reaction of adol condensation. The diamines were named as 1- （3-aminophenyl）-3- （4-aminophenyl）-2-propen-l-one and 1- （3-aminophenyl）-3- （4- （3- （3-aminophenyl）-3-oxo-l-propenyl） phenyl）-2-pro-pen-l-one. Best conditions for synthetic process were attained by the optimization of experiments as follows： diamines were synthesized from aldehyde and ketone dissolved in alcohol,adding sodium hydroxide as catalyst with continuous stirring for 3h at 0℃ with total yield over 86% and the purity were 99.92% and 99.91% respectively by the analysis of HPLC. The method had the advantages of cheapness, high yield and easy operation. Elemental analysis, HNMR and IR characterized the target compounds.
