Functional Hyperbranched Polythioamides Synthesized from Catalyst-free Multicomponent Polymerization of Elemental Sulfur
文献摘要:
Hyperbranched polymers with unique topological structures,large number of branching sites and terminal groups have attracted much attention,and are expected to possess advanced functionalities compared with their linear polymer counterparts.The devel-opment of hyperbranched polymers is hence highly desired but challenging,especially for sulfur-containing polymers which are at-tractive metal absorbents,optical materials,dielectric materials,and self-healing materials.In this work,six hyperbranched polythi-oamides with various topological structures,well-defined repeating units,satisfying yields(up to 99%),and high molecular weights(up to 101400 g/mol)were successfully designed and synthesized from the catalyst-free multicomponent polymerization of ele-mental sulfur,aromatic alkynes and aliphatic amines,through different monomer combination strategies based on the designed three-or four-functional alkyne and amine monomers.The hyperbranched polythioamides possess unique luminescence property,and strong affinity toward Hg2+,which can be utilized in the fluorescence detection of Hg2+,as well as mercury removal from aque-ous solutions with high efficiency of 99.99%and low mercury residue of 0.1 ppb.Hyperbranched polythioamides with unique struc-tures may be developed to a group of fascinating materials and find their potential applications as metal absorbents and optoelec-tronic materials.
