Benzoquinone Building Block for Developing Energy Storage Materials

Benzoquinone Building Block for Developing Energy Storage Materials

2,3,5,6-Tetraamino-1,4-benzoquinone (TABQ) [T4344] is a benzoquinone building block useful for developing energy storage materials. For instance, 2,3,7,8-tetraamino-5,10-dihydrophenazine-1,4,6,9-tetraone (1), synthesized through condensation of two TABQ molecules, has been reported as a promising organic cathode material for aqueous zinc and lithium-ion batteries¹),²). Its high electrical conductivity derives from electron delocalization and the redox activity of its carbonyl groups. TABQ is also used as a precursor for covalent organic frameworks (COFs) and polymers³),⁴). Because of its low solubility in electrolytes, TABQ itself has been reported as a cathode material for aqueous zinc batteries⁵).
