A simple approach to tune the optical properties of the hyperbranched conjugated polymers by only adjusting the terminal-backbone interactions has been reported in this article. Hyperbranched conjugated polyazomethines have been successfully prepared by the reaction of tetramine and dialdehyde. Not only varying the monomer feed ratio to change the quantity of terminal amino groups, but also adopting protonation or complexion with proper dopants (SnCl(2) and β-cyclodextrin), can alter the interactions between amino terminals and imine bonds in the backbone. Correspondingly, the optical properties of the resulting hyperbranched polymers are controlled.
本文报道了一种仅通过调节末端-主链相互作用来调控超支化共轭聚合物光学性质的简单方法。通过四胺和二醛的反应成功制备了超支化共轭聚甲亚胺。不仅可以通过改变单体进料比来改变末端氨基的数量，还可以通过用适当的掺杂剂（SnCl₂和β-环糊精）进行质子化或络合作用，来改变氨基末端与主链中亚胺键之间的相互作用。相应地，所得超支化聚合物的光学性质得到了控制。
