Electrochemical and electrochromic studies of redox-active aromatic polyamides with 3,5-dimethyltriphenylamine units

Electrosynthesis of Copolymers Based on 1,3,5-Tris(N-Carbazolyl)Benzene and 2,2′-Bithiophene and Their Applications in Electrochromic Devices

“…Organic redox-active materials have attracted great interest during the past decades for their potential applications in commercial electronic devices [ 1 , 2 , 3 ]. π-Conjugated polymers (CPs) have been recognized as an important class of organic redox-active materials.…”

“…In this section of our review we summarize the works published in this research field by Hsiao and coworkers [ 96 , 97 , 98 , 99 , 100 , 101 , 102 , 103 , 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 , 114 , 115 , 116 , 117 , 118 , 119 , 120 , 121 , 122 , 123 , 124 , 125 ], Sun et al [ 126 ] and He et al [ 127 ]. Electrochromic aramids are principally based on the polymerization of monomers that contain sub-structures that are the responsible for the reversible electrochemical oxidation processes accompanied with strong color changes of the polymer films prepared by casting, spin-coating or electropolymerization.…”

A Novel Electrochemical Sensor Based on Poly(1,5‐diaminonaphthalene) and Poly(1,2‐diaminoanthraquinone) Core‐shell Composite Electrodes for Effective Voltammetric Determination of Nitrite

“…As electrode materials, aromatic amine conducting polymers possess a unique capacity to generate stable compounds toward analytical targets [25]. Particularly, polydiaminonaphalenes such as poly(1,5-diaminonaphthalene) (pDAN) and poly(1,2-diaminoanthraquinone) (pDAAQ) have been studied as aromatic diamines for various applications, including the detection of heavy metals [26][27][28][29][30][31] and organic pollutants [32,33]. In this study, new modified electrodes were prepared by electrochemically depositing layer by layer pDAN and pDAAQ on a glassy carbon electrode (GCE) to generate pDAN/ pDAAQ@GCE and pDAAQ/pDAN@GCE shell-core composite electrodes of opposite composition for the determination of nitrite as mention in Scheme 1.…”
