Quinone molecular films derived from aminoquinones

Study of the DNA hybridization transduction behavior of a quinone-containing electroactive polymer by cyclic voltammetry and electrochemical impedance spectroscopy

“…The spectrum of the monomer presents a maximum at 425 nm, which shifts towards 535 nm for the polymer, indicating that the conjugation length is increased. This absorption band probably corresponds to the quinone moiety [25].…”

Significant effects of poly(3,4-ethylenedioxythiophene) additive on redox responses of poly(2,5-dihydroxy-1,4-benzoquinone-3,6-methylene) cathode for rechargeable Li batteries

“…This redox couple can be suitably used for the cathode material of lithium secondary batteries with high energy density [4][5][6][7][8]. Recently, Gall et al [9] have reported that a poly(quinone) derivative of poly(2,5-dihydroxy-1,4-benzoquinone-3,6-methylene) (PDBM) composited with 40% acetylene black (AB) demonstrates reversible redox cycle-ability with a specific capacity of 120-130 mAh g -PDBM quinone moieties but does not rise in the energy density.…”

Quinone-Based Polymers for Label-Free and Reagentless Electrochemical Immunosensors: Application to Proteins, Antibodies and Pesticides Detection

“…Other polymers were also used, and more particularly polyquinones, which present particular redox properties. For example, a series of aminonaphthoquinones and aminoanthraquinones were originally developed in the 80’s and 90’s for electrocatalytic purposes or energy storage [ 31 , 32 , 33 , 34 , 35 , 36 , 37 ]. More recently, other polyquinone films were developed to be used as transducers in biosensors [ 38 , 39 ].…”
