Conjugated Microporous Poly(aryleneethynylene) Networks

Abstract

Rigid wiry nets: Conjugated microporous polymer networks are formed by Sonogashira–Hagihara coupling. Although these materials are amorphous, the micropore size and surface area can be controlled by varying the length of the phenyleneethynylene struts (see picture; the network is shown in blue, and one 1,3,5‐substituted benzene node and three connected struts are highlighted with C gray and H white).

Microporous polymer network films covalently bound to gold electrodes

“…A gold surface was chosen as being a superior electrode and amenable to modification by SAMs. The gold surface was functionalized with 4-bromothiophenol since halogenated aromatic compounds are the moieties which are applied in the most frequently used C-C-bonding reactions for the synthesis of MPNs, such as the Sonogashira-Hagihara, 18 Yamamoto 19 or Suzuki 20 coupling. Provided that the forming polymer reacts with the exposed bromine atoms of the SAM, the formed MPN should be tightly connected to the surface by covalent bonds.…”

Porous Organic Polymers: A New Star in Porous Materials

“…2005 年以来, 纯 有机组分的共价有机多孔聚合物成为了多孔材料领域 的研究前沿 [4] , 尤其是 Yaghi 等人发展的晶型共价有机 框架材料 [5] 和 Cooper 等人发展的无定形共轭有机微孔 聚合物 [6] 引发了共价有机多孔聚合物的研究热潮. 共价有机多孔聚合物是一类完全由轻质元素(C、 H、 O、N、B 等)通过共价键的方式连接而成的有机多孔材 料.…”

“…一类是晶型的共价有机多 孔聚合物, 如共价有机框架材料 [7] (Covalent Organic Frameworks, COFs), 嗪 基 多 孔 聚 合 物 [8] (Covalent Triazine-based Frameworks, CTFs)等. 另一类是无定形 的共价有机多孔聚合物, 如固有微孔聚合物 [9] (Polymer of Intrinsic Microporosity, PIMs), 共轭微孔聚合物 [6] (Conjugated Microporous Polymers, CMPs), 超交联聚合 物 [10] …”

Targeted synthesis of electroactive porous organic frameworks containing triphenyl phosphine moieties

“…Recently, ultra high surface area covalent-linked porous organic frameworks (POFs) such as porous aromatic framework (PAF) [1][2][3][4][5], conjugated microporous polymer [6][7][8][9][10], covalent triazine-based framework [11], polymers of intrinsic microporosity [12,13], hyper-cross-linked polymer [14,15] and covalent organic framework [16][17][18] formed by organic polymerization method have emerged as an important platform in host-guest chemistry. The properties of POFs are crucially affected by their porosity when applied as a sorbent.…”
