Conducting polymers such as polycarbazole and its derivatives have attracted much attention due to their remarkable electrical optical properties. To prepare derivatives, a variety of substituents can be added the nitrogen atom carbazole monomers or 3- 6-positions. In present study, bearing hydrogen, methyl benzyl group at N-position styryl (naphthalen-1- -2-yl)vinyl 3-position were synthesized...
The colloidal dispersion in a nonpolar medium is an essential material for electrophoretic displays (EPD) with low-power consumption. A uniform-sized superparamagnetic iron oxide nanoparticle (SPION) promising candidate EPD, which exhibits tunable structural color by Bragg diffraction. In this study, the surface of SPION charged inverse micelles Solsperse-17k, oil-soluble polymeric surfactant. ...
Recently, with the continuous development of human society and innovation technologies, intelligence era has arrived. Various intelligent electronic devices continue to be developed, in which flexible wearable are highly favored by people. To meet requirements normal operation devices, key point lies new smart energy storage devices. Accordingly, supercapacitors have been widely focused on stud...
A uniform and crack-free metal−organic framework (MOF) thin film composed of free-standing acicular nanorods was grown on a transparent conducting glass substrate. The MOF thin film exhibits electrochromic switching between yellow and deep blue by means of a one-electron redox reaction at its pyrene-based linkers. The rigid MOF stabilizes the radical cations of the pyrene linkers at positive ap...
Different nanocomposites between reduced graphene oxide (rGO) and Ni(OH)2 nanoparticles were synthesized through modifications in the polyol method (starting from graphene oxide (GO) dispersion in ethylene glycol and nickel acetate), processed as thin films through the liquid-liquid interfacial route, homogeneously deposited over transparent electrodes and spectroscopically, microscopically and...
Tetraruthenium macrocycles with 1,4-divinylphenylene and diarylamine-substituted isophthalic acids as the sides display up to eight one-electron redox steps and rich electrochromic behaviour with strong absorptions of the dications in the near infrared and of the tetra- and hexacations at low energies in the visible.
