在本文中,我们描述了使用形成2,2,3,5,6-四氟对苯二甲腈生成二苯并二恶英的聚合反应,从含羟基的碗形“中心三茚满”和丙炔型“ triptindane”单体衍生的聚合物的合成和物理表征。通过氮吸附测量对所得聚合物的微孔率进行评估,发现表观的Brunauer-Emmett-Teller(BET)表面积在555-1039 m 2 g -1范围内,这可能与单体单元的独特形状有关。使用X射线晶体学对单体的形状进行评估有助于解释制备它们的聚合物的微孔程度。
characterized by X-raystructure analysis. Ozonolysis of 32 and 33 gives a keto ester (59) and a dimethyl muconate (60), respectively. Dimethoxytriptindane 34 gives a [3.3.3]propellane-cis,cis-muconate (61) in good yield, the stereochemistry of which is determined by X-raystructure analysis. Tetramethoxytriptindane 35 gives the [3.3.3]propellane-bis-muconate 62 along with a [3.3.3]propellane-dialdehyde-muconate

The first T-d-symmetrical derivative of centrohexaindanebearingtwelvefunctionalgroups has been synthesized. Six pairs of methoxy groups, each of which belong to six veratrole units fused to the topologically nonplanar (K-5) core, point outwards from the molecular center into the six directions of the Cartesian space. The synthesis of this first dodeca-substituted centrohexaindane was achieved along

In this paper we describe the synthesis and physical characterisation of polymers derived from hydroxyl containing bowl-shaped “centrotriindane” and propellane-type “triptindane” monomers using the dibenzodioxin-forming polymerisation reaction with 2,3,5,6-tetrafluoroterephthalonitrile. Evaluation of the microporosity of the resulting polymers via nitrogen adsorption measurements revealed apparent
