Microporous organic polymers (MOP) of a new type have been synthesised in high yields by a simple coordination polymerization of 1,3-diethynylbenzene, 1,4-diethynylbenzene and 4,4'-diethynylbiphenyl catalysed by [Rh(cod)acac] and [Rh(nbd)acac] complexes. The new MOPs are non-swellable polyacetylene-type conjugated networks consisting of ethynylaryl-substituted polyene main chains that are crosslinked by arylene linkers. Prepared MOP samples have a mole fraction of branching units (by (13)C CP/MAS NMR) from 0.30 to 0.47 and exhibit the BET (Brunaer-Emmett-Teller) surface up to 809 m(2) g(-1) and hydrogen uptake up to 0.69 wt% (77 K, H2 pressure 750 torr).
通过[Rh(cod)acac]和[Rh(nbd)acac]配合物催化1,3 - 二乙炔基苯、1,4 - 二乙炔基苯和4,4'-二乙炔基联苯进行简单的配位聚合反应，已高产率合成了一种新型微孔有机聚合物（MOP）。新型MOP是由乙炔基芳基取代的多烯主链组成的不可溶胀的聚乙炔型共轭网络，这些主链通过亚芳基连接基交联。制备的MOP样品的支化单元摩尔分数（通过(13)C CP/MAS NMR测定）为0.30至0.47，BET（布鲁诺尔 - 埃米特 - 特勒）比表面积高达809 m(2) g(-1)，在77 K、氢气压力750托的条件下氢气吸附量高达0.69 wt%。
