Název v původním jazyce

Chain-growth copolymerization of functionalized ethynylarenes with 1,4-diethynylbenzene and 4,4 '-diethynylbiphenyl into conjugated porous networks

Popis výsledku v původním jazyce

We report the synthesis of conjugated highly cross-linked polyacetylene-type networks with a high content of functional groups (-CH2OH, -NO2, -Ph2N, content up to 3.9 mmol/g) via a chain-growth copolymerization of either 1,4-diethynylbenzene or 4,4'-diethynylbiphenyl with functionalized mono- and diethynylbenzenes. The backbone of the networks consists of substituted polyene main chains that are cross-linked by arylene links. The optimized combinations of comonomers in the feed provide functionalized networks with a Brunauer-Emmett-Teller specific surface area up to 667 m(2)/g and enhanced affinity for CO2 adsorption (compared to the non-functionalized hydrocarbon networks of the same type). The dependence of the specific surface area of the networks on the size and architecture of the comonomers used for the synthesis is discussed in the paper. The reported networks can be classified into the group of conjugated microporous polymers (CMPs). Contrary to the CMPs synthesized by step-gro
