conjugated microporous polymer (CMP) that comprises pseudo-para-substituted [2.2]paracyclophane was prepared. The obtained CMP is regarded as a polymer, in which 1,3,5-tris[(2,5-dimethylphenyl)ethynyl]benzenes are infinitely stacked to form a network structure. The CMP exhibited a type I nitrogen gas sorption profile and an H4-like hysteresis loop, and possessed the slit-like mesopores with a BET surface
一种新的[2.2]对环烷烃化合物,由两个彼此叠置的1,3,5-三[[(2,5-二甲基苯基)乙炔基]苯组成。该化合物表现出独特的吸收带(环带谱带),并以谱带态发射,这两者均源自于1,3,5-tris [(2,5-二甲基苯基)乙炔基]苯。另外,制备了包含假对-对取代的[2.2]对环环烷的共轭微孔聚合物(CMP)。所获得的CMP被认为是聚合物,其中1,3,5-三[(2,5-二甲基苯基)乙炔基]苯无限地堆叠以形成网络结构。CMP表现出I型氮气吸附特性和类似H4的磁滞回线,并具有BET表面积为501 m的狭缝状中孔2 g -1。
