Zhong, Fuyao; Ma, Mingyu; Zhong, Zhuoran; Lin, Xinrong; Chen, Mao published an article in 2021. The article was titled 《Interfacial growth of free-standing PANI films: toward high-performance all-polymer supercapacitors》, and you may find the article in Chemical Science.SDS of cas: 4316-58-9 The information in the text is summarized as follows:
Along with high power capability and energy d., long cycle life is regarded an essential performance requirement for energy storage devices. The rapid capacitance decline of conducting polymer-based electrodes remains a major tech. challenge and precludes their practical applications in supercapacitors. In this work, a polyaniline (PANI) network is synthesized via interfacial Buchwald-Hartwig polymerization for the first time, facilitating the construction of covalently connected PANI networks by ligand-promoted C-N bond formation. Particularly, the interfacial synthesis and subsequent gas release from pre-anchored protecting groups allow bottom-up and efficient access to porous crosslinked PANI (PCL-PANI) films that are free-standing and solvent-resistant. Upon assembling into supercapacitors, the PCL-PANI material enables an unprecedent long-term charge-discharge cycling performance (>18 000 times) without clear capacitance loss for an additive-free pseudocapacitive system. In addition, this synthesis affords electrodes entirely consisting of conducting polymers, yielding highly reversible gravimetric capacitance at 435 F gelectrode-1 in a two-electrode system, and a high gravimetric energy of 12.5 W h kgelectrode-1 while delivering an outstanding power d. of 16 000 W kgelectrode-1, which is 10-fold higher than those of conventional linear PANI composite supercapacitors. This synthetic approach represents a novel and versatile strategy to generate additive/binder-free and high-performance conducting thin-films for energy storage. In the experiment, the researchers used Tris(4-bromophenyl)amine(cas: 4316-58-9SDS of cas: 4316-58-9)
In general, Tris(4-bromophenyl)amine(cas: 4316-58-9) is often used in the synthesis of porous luminescent covalent–organic polymers (COPs)SDS of cas: 4316-58-9
