“…In the first cycle measured at a low scan rate of 100 mV·s -1 , higher specific capacitances were obtained; that is, about 160 F·g -1 for the composite electrode with activated carbon and DAQ, and about 100 F·g -1 and 45 F·g -1 for the electrode adopting activated carbon and DAQ, respectively. It is notable that the specific capacitance of DAQ can be greatly increased (45 F·g -1 to 160 F·g -1 ) by compositing with activated carbon, compared with a small increase (110 F·g -1 to 130 F·g -1 ) in HBU [15]. This is probably due to the difference in the electrical conductivity between DAQ and HBU as a major factor, and in the surface morphology as a minor factor.…”

“…It was also notable that quinone-containing organic species might play a role in enhancing the supercapacitive properties from their redox-active behaviors through a quinone-hydroquinone transition [3]- [14]. Moreover, an activated carbon supercapacitor adopting 2,5-bis((2-(1H-indole-3-yl)ethyl) amino)cyclohexa-2,5-diene-1,4-dione (HBU) as a quinonecontaining conducting additive was recently proved to achieve a higher specific capacitance of 130 F·g -1 within the range of 100 mV·s -1 to 1,000 mV·s -1 [15]. The addition of the HBU was beneficial in the enhancement of the electrochemical stability of the electrolytes and the cycle performance of the supercapacitor.…”

“…It can thus be expected that the use of a conducting compound consisting of aminopyrene and quinone components would be a promising additive for enhancing the electrochemical performance of an activated carbon supercapacitor, similar to the case of using HBU as a conducting additive [15]. That is, the adoption of aminopyrene as a source compound of an additive with quinone, instead of tryptamine [15], will be more beneficial because the aminopyrene has its own conducting property [17], [18] and the synergistic effect in the supercapacitive properties can be expected by combining with quinone as another conducting component.…”

“…The electrochemical properties of the symmetric supercapacitor fabricated using composite electrodes are characterized using a cyclic voltammetric measurement. Further enhancements of the supercapacitive performance can be expected by including DAQ, rather than adopting HBU [15].…”

Di(1-aminopyrene)quinone (DAQ) as a quinonecontaining conducting additive is synthesized from a solution reaction of 1-aminopyrene and hydroquinone. To utilize the conductive property of DAQ and its compatibility with activated carbon, a composite electrode for a supercapacitor is also prepared by blending activated carbon and DAQ (3:1 w/w), and its supercapacitive properties are characterized based on the cyclic voltammetry and galvanostatic charge/discharge. As a result, the composite electrode adopting DAQ exhibits superior electrochemical properties, such as a higher specific capacitance of up to 160 F·g -1 at 100 mV·s -1, an excellent high-rate capability of up to 1,000 mV·s -1 , and a higher cycling stability with a capacitance retention ratio of 82% for the 1,000th cycle.

The preparation of new mono-and bis-NH-substituted-1,4-benzoquinones, namely 2,5bis (5,6-dimethylbenzo[d]thiazol-2-ylamino)cyclohexa-2,5-diene-1,4-dione (3), 2,5-bis(3-(2methylpiperidin-1-yl)propylamino)-3-chlorocyclohexa-2,5-diene-1,4-dione (6), 2-(4-tertbutylbenzylamino)-3,5,6-trichlorocyclohexa-2,5-diene-1,4-dione (9), 2-(4-fluorophenylamino)-6tert-butylcyclohexa-2,5-diene-1,4-dione (12) are reported. The synthesis of new quinone derivatives (3, 6, 9, 12) have been carried out from the reactions between quinones (pbenzoquinone (1), 2,6-dichloro-1,4-benzoquinone (4), tetrachloro-1,4-benzoquinone (7) or 2-tertbutyl-1,4-benzoquinone (10)) and different amines (2-amino-5,6-dimethylbenzothiazole (2), N-(3aminopropyl)-2-pipecoline (5), 4-tert-butylbenzylamine (8) or 4-fluoroaniline (11)). The new compounds were characterized by elemental analysis, mass spectrometry, IR, 1 H-NMR, 13 C-NMR spectroscopy.Cite this: Kaçmaz A. Synthesis of Some Mono-, Bis-NH-substituted-1,4-Benzoquinones.

Due to their prominent power density, supercapacitors carve out a niche among all the energy storage systems. However, it is also well known that the energy density of supercapacitors takes no advantage over lithium‐ion batteries, the current star energy storage device. Therefore, substantial efforts have been paid to improving the energy density of supercapacitors not at the expense of its power density. To develop electrode with high capacitance is a direct and efficient way to increase the energy storage capability of supercapacitors. Organics whose molecular structure can be diversely designed to achieve high pseudocapacitance arising from redox active units in their backbone are good candidates as electrode materials for supercapacitors. Herein, this review summarizes recent progress of redox‐active organic electrode materials for supercapacitors and their pseudocapacitive energy storge mechanisms based on different organic functional groups. From the aspects of their preparation approaches, molecular design and the resultant electrochemical performances, the focus is to probe the relationship between the energy storage mechanisms and the molecular structure of redox‐active units and provide some insights for the further development of organic supercapacitor electrodes.
