Nitrogen-rich conjugated microporous polymers (CMPs) with tunable porosities and reversible redox properties have received increasing interest as electrode materials for supercapacitors. Herein, pyridyl building blocks with different substitutions are selected to synthesize four amine-linked conjugated microporous polytriphenylamine (PTPA) networks via Buchwald-Hartwig cross-coupling reaction engineering the redox activity of PTPAs. The structures, porosities, and redox activities of these four PTPAs are investigated. The electrochem. characterization results show that PTPA obtained using 2,5-diaminopyridine dihydrochloride (i.e., PTPA-25) displays the highest specific capacitances ≤ 335 F g-1 in 1.0 M H2SO4 at a c.d. of 0.5 A g-1. Upon 5000 cycles, PTPA-25 maintains good initial capacitances ≤ 65%, nearly 100% Coulombic efficiencies at a c.d. of 2 A g-1, and high rate properties (remained a high capacitance of 250 F g-1 at 10 A g-1). The effect of different substitutions of pyridyl on the redox activities of the synthesized PTPA electrodes is further proposed, which would give insight into engineering the performance of CMPs-based supercapacitors.2,6-Diaminopyridine(cas: 141-86-6Name: 2,6-Diaminopyridine) was used in this study.
2,6-Diaminopyridine(cas: 141-86-6) belongs to pyridine. Pyridine and its simple derivatives are stable and relatively unreactive liquids, with strong penetrating odours that are unpleasant.Name: 2,6-Diaminopyridine
