Segment block dendrimers consisting of polyester and polyaryl ether dendrons were synthesized using reagent free Diels-Alder cycloaddition reactions. Three generations of furan functionalized polyaryl ether dendrons were reacted with maleimide functionalized polyester dendrons of the same generation to obtain segment block dendrimers in good yields. The thermoreversible nature of these macromolecules was investigated by subjecting them to elevated temperatures in the presence of anthracene as a scavenger diene.
使用无试剂狄尔斯-阿尔德环加成反应合成了由聚酯和聚芳醚树枝状分子组成的嵌段树枝状大分子。三代呋喃官能化的聚芳醚树枝状分子与同代的马来酰亚胺官能化的聚酯树枝状分子反应,以高收率获得嵌段树枝状大分子。通过在蒽作为清除二烯存在的情况下将这些大分子置于高温下,研究了它们的热可逆性质。
