Conjugated microporous poly(phenylene butadiynylene)s

Abstract

High surface area porous poly(phenylene butadiynylene) networks were obtained (BET surface area up to 842 m(2) g(-1)) by the palladium-catalyzed homocoupling of 1,3,5-triethynylbenzene and 1,4-diethynylbenzene.

First-Principles Investigation of Li⁺-doped Conjugated Microporous Polymer as a Potential Hydrogen Storage Medium

“…32. The ultrahigh porosity and amorphous property are clearly illustrated, and the Brunauer-Emmet-Teller (BET) surface area was assessed to be as high as about 842 m 2 /g [32]. It should be note that the advantage of alkali metals over other metal elements is that the isolated form is preferred over clustering, and lithium selected in this work has accessional superiority as it is the lightest metal element.…”

“…So far, there are lack of pertinent investigations on polymer systems, partially because of their amorphism in nature and low thermal stability. Very interestingly, a new family of rigid conjugated microporous polymer (CMP) using triethynylbenzene as building block were synthesized by Cooper et al [32,33], who claimed that the CMP has very good chemical and thermal stability and retention of microporosity under a variety of conditions, moreover, the physical properties like micropore size and surface area can be fine tuned by varying the monomer strut.…”

“…Schematic diagram, Figure 1, displays the CMP under research; the polymer network is chosen the same as the homocoupled conjugated microporous polymer produced from 1,3,5-triethynylbenzene (HCMP-1) reported in Ref. 32. The ultrahigh porosity and amorphous property are clearly illustrated, and the Brunauer-Emmet-Teller (BET) surface area was assessed to be as high as about 842 m 2 /g [32].…”

Conjugated Microporous Polymer‐Derived Porous Hard Carbon as High‐Rate Long‐Life Anode Materials for Lithium Ion Batteries

“…In particular, traditional synthesis methods involving the carbonization of low-vapor-pressure polymeric precursors 19,21] or natural sources [20] have their respective drawbacks, which are mostly associated with cross-linking reactions that proceed with concomitant char formation or uncontrolled vaporization during high-temperature pyrolysis. [22] Conjugated microporous polymers (CMP) have received considerable research interest because of their 3D interlinked porous structure, large Brunauer-Emmett-Teller (BET) specific surface areas, and good chemical stability [23][24][25][26][27][28][29][30][31][32][33] with regard to potential applications for the selected adsorption of organic solvents [24] and gas adsorption. [25][26][27][28][29][30][31][32][33] More interestingly, the surface areas and pore volumes of the CMP could be easily tuned by using different monomers with various molecule lengths, making them ideal candidates for preparation of porous carbon.…”

“…[23,[30][31][32] Then, CMP-1 was calcined at 400 8C for 2 h, then kept at 700 8C for 4 h to obtain the porous hard carbon (PHC-1). Computational simulations show that CMP-1 has a porous three-dimensional network structure arising from the three-pronged butadiynylene linkages (Figure 1 a).…”
