Design, preparation and application of conjugated microporous polymers

Abstract

Conjugated microporous polymers (CMPs) are of great interest because these types of materials have high specific surface area and pore diameters less than 2 nm. CMPs have found applications in the fields of hydrogen storage, heterogeneous catalysts, gas-permeable membranes and light-emitting organics. A large number of recent reports have demonstrated that CMPs can be prepared using several approaches like noble metal-mediated ethynyl, Sonogashira-Hagihara coupling, Suzuki coupling and Yamamoto coupling reactions. In this review, the synthetic routes, functionalization and potential applications of CMPs are systematically introduced.

Transition‐Metal‐Catalyzed Chain‐Growth Polymerization of 1,4‐Diethynylbenzene into Microporous Crosslinked Poly(phenylacetylene)s: the Effect of Reaction Conditions

“…Some of these reactions have recently been modified by increasing the functionality of monomer(s) applied for the synthesis, and several types of MOPs based on acetylene monomers have been prepared. Highly conjugated poly(arylenebutadiynylene) and poly(arylene‐ethynylene) networks prepared via step‐growth Pd‐catalyzed couplings are the best known MOPs of this type. The starting materials for these networks were either a mixture of multiethynylarenes (MEAs) or a mixture of MEAs with (multibromo)arenes or (multiiodo)arenes (average functionality of monomers, f > 2).…”

Kovalente organische Gerüstverbindungen: chemische Ansätze für Designerstrukturen und integrierte Funktionen

“…Eine Polykondensation kann auch amorphe poröse Polymere ergeben, z. B. poröse organische Polymere und konjugierte mikroporöse Polymere (CMPs) . Diese Polymere bestehen aus 3D‐vernetzten Strukturen und bilden schwerlich kristalline Materialien.…”

In Situ Growth of Flexible Polyphenylene-Conjugated Microporous Polymer Films for Fluorescence Detection of the Total Quantity of Developing Agents and Their Oxidation Products

“…Conjugated microporous polymers (CMPs) [1], linked by covalent bond to form extension of aromatic ring skeletons, are microporous materials characterized by extended conjugated structure and permanent microporosity. Different from traditional microporous materials such as zeolite and activated carbon, CMPs have been elaborated integration of p-electronic components to the covalent framework, which would have a decisive influence on fluorescence properties of CMPs.…”
