摘要
以4,4’-二甲基二苯甲酮为原料,经过溴化、选择性胺化、O-烷基化等反应,依次合成了4-(溴甲基)-4’-[双(羟乙基)氨基]二苯甲酮与4-(腰果酚基甲基)-4’-[双(羟乙基)氨基]二苯甲酮两个功能性的类米氏酮光引发剂,收率分别为58%和46%。在4-(溴甲基)-4’-[双(羟乙基)氨基]二苯甲酮中含有苄溴基团,因此该化合物还可作为ATRP或SET-LRP引发剂。同时,利用4-(溴甲基)-4’-[双(羟乙基)氨基]二苯甲酮作引发剂进行了腰果酚单体的AGET ATRP聚合反应,得到相应的腰果酚均聚物(Mn=20.2 k Da,PDI=1.11)。小分子化合物的结构用1H-NMR进行了表征。
By using 4,4’-dimethyl benzophenone as starting material,two functional Michler’s ketonelike photoinitiators,4-(bro-momethyl)-4’[bis(hydroxyethyl)amino]benzophenone and 4-(cardanolylmethyl)-4’-[bis(hydroxyethyl)amino]benzophenone were synthesized via bromination,selective amination and O-alkylation.The yields were 58%and 46%,respectively.The compound 4-(bromomethyl)-4’-[bis(hydroxyethyl)amino]benzophenone could act as an ATRP or SETLRP initiator,because there was an benzyl bromide group in this compound.Furthermore,AGET ATRP polymerization of cardanyl methacrylate was conducted by using 4-(bromomethyl)-4’-[bis(hydroxyethyl)amino]benzophenone as the initiator,leading to the corresponding cardanolbased homopolymer(Mn=20.2 kDa,PDI=1.11)Structures of the synthesized small molecules were characterized by 1 H-NMR.
