Pyrene-based covalent organic polymers with nano carbonaceous composites for efficient supercapacitive energy storage

Abstract

We prepared Py-DSDA-COP/SWCNTs and this material showed a capacitance of 171 F g−1 and energy density of 23.7 W h kg−1 which is superior to those of Py-DSDA-COP/MWCNTs and Py-DSDA-COP/C60 nanocomposites.

Conjugated microporous polymers: their synthesis and potential applications in flexible electrodes

“…43 The Sonogashira–Hagihara cross-coupling reaction allows the introduction of lightweight alkyne/olefin support units, thereby enabling the formation of conjugated polymers characterized by high specific surface area and stable micropores. 40 In 2014, Jiang et al 44 synthesised a newly designed hexaazatrinaphthalene conjugated microcellular polymer (HATN-CMP) via the Sonogashira–Hagihara coupling reaction, which was used as energy storage for lithium-ion batteries (LIBs) (Fig. 2a and b).…”

Bifunctional imidazolium linked tetraphenylethene based conjugated microporous polymers for dynamic antibacterial properties and supercapacitor electrodes

“…28,29 One standout solution is the supercapacitor, known for its outstanding speed capabilities, safe operation, maximal capacity, environmentally friendly attributes, prolonged cycle stability, minimal fabrication cost, and high power density. 30–32 Supercapacitors (SCs) are categorized into electrochemical pseudocapacitors and electric double-layer capacitors (EDLCs) based on their charge-storing mechanisms. 33,34 Pseudocapacitors store energy through highly reversible redox interactions between electrolyte ions and electrode materials.…”

Ultrathin alkynylation phthalocyanine-conjugated organic polymer nanosheets for constructing a sensitive electrochemiluminescence sensor

“…Consequently, COPs have also been exploited in the photoelectric field. COPs have been evaluated for photoredox catalysis, 8–10 supercapacitors, 11,12 and batteries. 13,14 Furthermore, the microporosity and extended π-conjugation in COPs are conducive to storing electrical energy in electrodes.…”
