Electrochromic Behavior(电致变色行为)研究综述
Electrochromic Behavior 电致变色行为 - Besides, the electrochromic behaviors of the obtained AgNW/TPPA hybrid electrode demonstrated obvious multicolor appearance changes during their two oxidation stages. [1] Electrochromic behaviors of the polymers suggested that P[Z-Th2TTpTPE] has promising electrochromic properties with high coloration efficiency of 309 cm2 C−1. [2] However, the electrochromic behaviors of metallic nanoparticles in narrow optical windows have been demonstrated only with small monotonic LSPR shifts, which limits the use of the electrochromism. [3] The electrochromic behaviors of the ECDs were investigated using cyclic voltammetry, chronoamperometry and transmittance measurements. [4] Two novel selenophenothiophene homopolymers, P(SeT1) and P(SeT2), were electrochemically prepared for the first time from their corresponding monomers (i) conjugated 2,5-di(thiophen-2-yl)selenopheno[3,2-b]thiophene (1) and (ii) cross-conjugated 2,5-di(thiophen-2-yl)selenopheno[2,3-b]thiophene (2) to explore their electrochromic behaviors. [5] On the other hand, for colorimetric measurements, electrochromic behavior of the proposed aptasensor could be adjusted by the hinder effect induced by specific binding between aptamers and ATP. [6] Electrochromic behavior of both polymers was comparatively investigated by employing a three-electrode cell and «smart windows» prototypes. [7] Electrochromic power storage devices integrate energy storage and electrochromic behavior into a single full cell that can enable the visualization of the energy status by the naked eyes. [8] In addition, PI-1a film with asymmetric structure also demonstrates fast electrochemical and electrochromic behaviors (a switching and bleaching time of 1. [9] The newly formed dimer tetra-N-phenyl benzidine (TPB) exhibits multi-electrochromic behavior, from colorless TPB0 via the bronze colored radical TPB+•, and further to green TPB2+ species. [10] In this work, we report the role of structure on electrochromic behavior of nickel oxide thin coatings deposited via chemical vapor deposition on ITO-coated glass in (EtCp)2Ni–O2–Ar and (EtCp)2Ni–O3–O2–Ar reaction systems. [11] The copolymer has a multielectrochromic behavior: It has dark purple, purple, gray, green and cyan colors at different oxidation states. [12] The influence of this architecture on the stability, electrochemical and electrochromic behavior was thoroughly studied. [13] Two novel triphenylamine-based derivatives with dimethylamino substituents, N, N'-bis(4-dimethylaminophenyl)- N, N'-bis(4-methoxyphenyl)-1,4-phenylenediamine (NTPPA) and N, N'-bis(4-dimethylaminophenyl)- N, N'-bis(4-methoxyphenyl)-1,1'-biphenyl-4,4'-diamine (NTPB), were readily prepared for investigating the optical and electrochromic behaviors. [14] The electrochromic behavior of these 2D and 3D IO samples was investigated. [15] Hence, we can conclude that the effects of the electrochromic behavior of the conjugation-broken polythiophene derivatives depend on the increased conjugation length of the thiophene repeating unit, in which the inadequate electrochromism with bithiophene units can change to superior electrochromic properties with increased sexithiophene units. [16] In this study, the electrochromic behavior of benzonitrile compounds were investigated. [17] We present effects of counter anions on electrochromic behavior of asymmetrically substituted viologens, 1-hexyl-1′-nonafluorohexyl viologens (HERFVs). [18] Furthermore, the electrochromic behavior of PEDOT/Ti3C2Tx microsupercapacitors was investigated using in-situ UV–vis and resonant Raman spectroscopies. [19] The electrochromic properties of these materials can be modulated by varying the nitrogen substituents on the pyridyl ‘N’; also, besides this, varying the counter ions with specific functionalities has been shown to enhance the electrochromic behavior, such as switching time, cycling stability and device performance. [20] The effects of RGO concentration on the morphology, chemical structure, crystallinity, and electrochromic behavior of the composite membranes were studied. [21] In this study, we newly synthesized iron phthalocyanine incorporated iron metallo-supramolecular polymers (Pc-Fe-polymer) and investigated its electrochromic behavior in both solution and solid-sta. [22] Furthermore, POV film displays approving dual-electrochromic behavior in both anodic and cathodic potential areas with desirable contrast value, moderate switching times, and acceptable coloration efficiency. [23] This research study presents a comprehensive overview of the electrochemical synthesis of nanoporous Cu-doped nickel oxide films on ITO-coated glass substrate and its electrochromic behavior in alkaline medium. [24]此外，所获得的 AgNW/TPPA 杂化电极的电致变色行为在两个氧化阶段表现出明显的多色外观变化。 [1] 聚合物的电致变色行为表明 P[Z-Th2TTpTPE] 具有良好的电致变色性能，具有 309cm2 C-1 的高着色效率。 [2] 然而，金属纳米粒子在窄光学窗口中的电致变色行为仅通过小的单调 LSPR 位移得到证明，这限制了电致变色的使用。 [3] 使用循环伏安法、计时电流法和透射率测量来研究 ECD 的电致变色行为。 [4] 两种新型硒吩噻吩均聚物 P(SeT1) 和 P(SeT2) 首次由其相应的单体 (i) 共轭 2,5-di(thiophen-2-yl)selenopheno[3,2-b] 电化学制备. 噻吩 (1) 和 (ii) 交叉共轭 2,5-二(噻吩-2-基)硒酚[2,3-b]噻吩 (2) 以探索它们的电致变色行为。 [5] 另一方面，对于比色测量，所提出的适体传感器的电致变色行为可以通过适体与 ATP 之间的特异性结合引起的阻碍效应来调整。 [6] 通过采用三电极电池和“智能窗”原型对两种聚合物的电致变色行为进行了比较研究。 [7] 电致变色储能装置将能量存储和电致变色行为集成到一个完整的电池中，可以通过肉眼实现能量状态的可视化。 [8] 此外，具有不对称结构的 PI-1a 薄膜还表现出快速的电化学和电致变色行为（切换和漂白时间为 1. [9] 新形成的二聚四-N-苯基联苯胺（TPB）表现出多电致变色行为，从无色TPB0到青铜色自由基TPB+•，再到绿色TPB2+物种。 [10] 在这项工作中，我们报告了在 (EtCp)2Ni-O2-Ar 和 (EtCp)2Ni-O3-O2-Ar 反应系统中通过化学气相沉积在 ITO 涂层玻璃上沉积的氧化镍薄涂层的电致变色行为的结构的作用。 . [11] 该共聚物具有多电致变色行为：在不同氧化态下具有深紫色、紫色、灰色、绿色和青色。 [12] 深入研究了这种结构对稳定性、电化学和电致变色行为的影响。 [13] 两种具有二甲氨基取代基的新型三苯胺衍生物，N,N'-双(4-二甲氨基苯基)-N,N'-双(4-甲氧基苯基)-1,4-苯二胺(NTPPA)和N,N'-双( 4-二甲基氨基苯基)-N, N'-双(4-甲氧基苯基)-1,1'-联苯-4,4'-二胺 (NTPB) 很容易制备用于研究光学和电致变色行为。 [14] 研究了这些 2D 和 3D IO 样品的电致变色行为。 [15] 因此，我们可以得出结论，共轭断裂聚噻吩衍生物的电致变色行为的影响取决于噻吩重复单元的共轭长度增加，其中与二噻吩单元不充分的电致变色可以随着六噻吩单元的增加而转变为优异的电致变色性能。 [16] 在本研究中，研究了苯甲腈化合物的电致变色行为。 [17] 我们提出了抗衡阴离子对不对称取代紫精、1-己基-1'-九氟己基紫精 (HERFV) 电致变色行为的影响。 [18] 此外，使用原位紫外可见光谱和共振拉曼光谱研究了 PEDOT/Ti3C2Tx 微型超级电容器的电致变色行为。 [19] 这些材料的电致变色特性可以通过改变吡啶基‘N’上的氮取代基来调节；此外，除此之外，改变具有特定功能的抗衡离子已被证明可以增强电致变色行为，例如切换时间、循环稳定性和器件性能。 [20] 研究了RGO浓度对复合膜的形貌、化学结构、结晶度和电致变色行为的影响。 [21] 在这项研究中，我们新合成了掺有铁金属超分子聚合物（Pc-Fe-polymer）的铁酞菁，并研究了它在溶液和固相中的电致变色行为。 [22] 此外，POV 薄膜在阳极和阴极电位区域都显示出令人认可的双电致变色行为，具有理想的对比度值、适中的切换时间和可接受的着色效率。 [23] 本研究全面概述了在 ITO 涂层玻璃基板上电化学合成纳米多孔 Cu 掺杂氧化镍薄膜及其在碱性介质中的电致变色行为。 [24]
44′ bipyridinium dibromide 44'联吡啶二溴化物
In order to investigate the effect of alkyl substituents on electrochromic behavior, four alkyl-substituted viologens and a benzyl-substituted viologen were synthesized, namely 1,1′-dioctyl-4,4′-bipyridinium dibromide (OV), 1,1′-didekyl-4,4′-bipyridinium dibromide (DeV), 1,1′-didodecyl-4,4′-bipyridinium dibromide (DoV), 1,1′-dihexadecyl-4,4′-bipyridinium dibromide (HV), and 1,1′-dibenzyl-4,4′-bipyridinium dibromide (BV). [1]为了研究烷基取代基对电致变色行为的影响，合成了四种烷基取代紫精和一种苄基取代紫精，即1,1'-二辛基-4,4'-联吡啶二溴化物（OV）、1,1' -didekyl-4,4'-bipyridinium dibromide (DeV), 1,1'-didodecyl-4,4'-bipyridinium dibromide (DoV), 1,1'-dihexadecyl-4,4'-bipyridinium dibromide (HV),和 1,1'-dibenzyl-4,4'-bipyridinium dibromide (BV)。 [1]
