Chain-Growth Insertion Polymerization of 1,3-Diethynylbenzene High Internal Phase Emulsions into Reactive ? - Conjugated Foams

Popis výsledku v původním jazyce

The ?-conjugated micro/macroporous polyacetylene-type polyHIPE foams were synthesized for the fi rst time by a chain-growth insertion polymerization of high internal phase emulsions (HIPEs). In the first step, the ?-conjugated polyHIPE foams were prepared by polymerization of 1,3-diethynylbenzene HIPEs using [Rh(nbd)acac] complex as a catalyst. The ? -conjugated polyHIPE foams consist of ethynylphenyl-substituted polyene main chains which are cross-linked by the 1,3-phenylene linkers. In the second step, the foams were chemically and thermally postmodified by applying the alkyneMINUS SIGN azide cycloaddition reaction and the solvent free solid phase hyper-cross-linking at temperature of 280oC. Thus, obtained polyacetylene-type polyHIPE foams exhibit hierarchically structured micro/macroporous morphology with sizes of the macropores and interconnecting pores of 3.4 +- 0.3 ?m (or 4.8 +- 0.8 ?m) and 0.96 ?m (or 1.1 ?m), respectively, wherein a substantial volume of micropores is also foun
