Embodiment 1

[0139] (1) Synthesis of 2-iodophenanthrene-9,10-dione

[0140] In an eggplant-shaped flask with a capacity of 200ml, add 10.0g of 9,10-phenanthrenequinone, 54.8g of trifluoroacetic acid and 21.6g of N-iodosuccinimide at room temperature, raise the temperature to 35°C, and then stir in an argon atmosphere 36 hours. The reaction mixture was poured into ice water, and the precipitated solid was filtered off and recrystallized using tetrahydrofuran to obtain 12.1 g of 2-iodophenanthrene-9,10-dione as an orange solid (yield 75%).

[0141] (2) Synthesis of 9,10-bis(tert-butyldimethylsilyloxy)-2-iodo-9,10-dihydrophenanthrene

[0142] In an eggplant-shaped flask with a capacity of 200ml, add 1.0g of 2-iodophenanthrene-9,10-dione, 3.0g of zinc powder, 100ml of dichloromethane, N,N,N',N'-tetramethylethylenediamine 1.8 g and 1.9 g of tert-butyldimethylsilyl chloride (hereinafter referred to as "TBDMSCl") were stirred overnight at room temperature in an argon atmosphere. 1.0 g of TBDMS...

Embodiment 2

[0151] (1) 9,10-bis(tert-butyldimethylsilyloxy)-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolane Synthesis of -2-yl)-9,10-dihydrophenanthrenequinone

[0152] In a 100ml eggplant-shaped flask, add 9,10-bis(tert-butyldimethylsilyloxy)-2-iodo-9,10-dihydrophenanthrenequinone 6.4g and dehydrated ether 50ml, cool to -78°C. 9.5 ml of tert-butyllithium (1.31 mole n-pentane solution) was added dropwise to the cooled solution, and the mixture was stirred for 1 hour. 2.6 ml of 2-isopropoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane was added to the mixture, and the temperature was further gradually raised to room temperature while stirring. The resulting reaction mixture was subjected to column purification (filler: neutral granular silica gel, solvent: hexane: ethyl acetate = 10:1), and concentrated to obtain the compound represented by the following chemical structural formula as a white solid: 9,10-bis(tert-butyldimethylsilyloxy)-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolane-2- Base)-9,10-dih...

Abstract

A specific quinone compound, which contains two quinone groups at ortho positions and has such a characteristic that an electron transfer is caused during a reversible oxidation-reduction reaction, is oligomerized or polymerized. Consequently, there is obtained a novel organic compound which is insoluble in an organic solvent, while having high energy density. This novel organic compound is useful as an electrode active material for electrical storage devices. By using this organic compound as an electrode active material, there can be obtained an electrical storage device having higher energy density, lighter weight, smaller size and higher functions.

Description

technical field [0001] The invention relates to a phenanthrenequinone compound, an electrode active material and an electrical storage device. More specifically, the present invention mainly relates to the improvement of electrode active materials. Background technique [0002] Recent advances in electronic technology have brought significant popularity of portable electronic devices such as portable phones, portable personal computers, portable information terminals (Personal Data Assistance, PDA), and portable game machines. Along with this, demand for power storage devices such as secondary batteries that can be repeatedly charged and discharged has increased as a power source for portable electronic devices. Among them, a lithium secondary battery using lithium ions as a transfer carrier is widely used as a power source for portable electronic devices because of its high electromotive force and energy density, and is easy to adapt to miniaturization. [0003] In order ...
