摘要:
在假高稀释条件下,三官能团酮活化的氟碳化合物与双或三苯氧基化合物发生缩聚反应,产生了一系列非常大的大环芳香族醚酮;通过核磁共振、MALDI-TOF MS 以及 X 射线晶体学(将羰基还原为亚甲基连接后)对这些材料进行分离和表征,证实了通常会导致高支化或交联聚合物的缩聚反应也会产生大型闭合网络分子。

3,5-tris-(4-fluorobenzoyl)benzene with 3,3′-diindolylmethane via a catalyst-free nucleophilicsubstitution reaction. Due to the local dipole–π interactions between indole and carbon dioxide (CO2), the uptake capacity for CO2 reaches up to 16.0 wt% (1.0 bar, 273 K), and the high (CO2/N2 = 15, CO2/CH4 = 32) selectivities of the polymer make it a promising material for potential application in gas separation

A recyclable indole-based POP was successfully achieved, which was capable of visual colorimetric iodine capture in water via cation–π and electrostatic interactions.
The unusual transformation of β-aryl-β-haloacroleins into valuable triaroylbenzenes is reported by the first time. The convenient sequence takes advantage on the one step access to triaroylbenzenes. This work establishes that the presence of amine is required for the trimerization procedure since it is involved in the formation of iminium–enamine intermediate A.
Non-covalent dimerisation of a bicyclic aromatic oligomer via loop–loop interlocking in the solid state

A macrobicyclic ether-ketone oligomer containing twenty aromatic rings has been isolated from the products of nucleophilic condensation between 4,4â²-(9-fluorenylidene)diphenol and 1,3,5-tris(4â²-fluorobenzoyl)benzene. Reduction of all six carbonyl groups to methylene units yields a derivative which exhibits non-covalent dimerisation in the crystalline state via shape-complementary interlocking of fluorenylidene-containing âloopâ regions.
