Abstract
Two novel thermosensitive benzyl ether dendrimer with oligoethyleneoxy chains,tert-butyl 3,5-bis{2-[2-(2-methoxyethoxy)ethoxy]ethoxy}phenylcarbamate(4) and tert-butyl 3,5-bis{3,5-bis{2-[2-(2-methoxyethoxy)ethoxy]ethoxy}benzyloxy}phenylcarbamate(7),were desinged and synthesized from 5-aminoresorcinol.The structures were characterized by 1H NMR,13C NMR,IR and ESI-HR-MS.The solution properties of 4 and 7 were investigated by UV-vis.The results showed that 4 and 7 exhibited thermosensitivity,and the turbidity decreased with increasing concentrations.
