Fabrication of One-Dimensional Organic Nanomaterials and Their Optoelectronic Applications

Abstract

This paper reviews the recent research and development of one-dimensional (1D) organic nanomaterials synthesized from organic semiconductors or conducting polymers and their applications to optoelectronics. We introduce synthetic methodologies for the fabrication of 1D single-crystalline organic nanomaterials and 1D multi-component organic nanostructures, and discuss their optical and electrical properties. In addition, their versatile applications in optoelectronics are highlighted. The fabrication of highly crystalline organic nanomaterials combined with their integration into nanoelectronic devices is recognized as one of the most promising strategies to enhance charge transport properties and achieve device miniaturization. In the last part of this review, we discuss the challenges and the perspectives of organic nanomaterials for applications in the next generation soft electronics, in terms of fabrication, processing, device integration, and investigation on the fundamental mechanisms governing the charge transport behaviors of these advanced materials.

Tailoring the Diameters of Polyaniline Nanofibers for Sensor Application

“…34−36 Emulsion and precipitation techniques are the two main choices for the preparation of polymer nanoparticles, and with both these techniques it is difficult to control the size and shape of the polymers. 34−36 Therefore, we proposed that the size of the polymer nanoparticles could be tuned by controlling at the assembly step before polymerization, because the assembly of small molecules (monomers) is more precise than polymers. In the present work, we demonstrated that the diameters of PANI nanofibers could be tuned by controlling the assembly of monomers (anilines) before polymerization.…”

One-Dimensional Nanostructure Engineering of Conducting Polymers for Thermoelectric Applications

“…A variety of 1D nanostructured materials based on P3AT have been prepared by different kinds of approaches. It has been reported that continuous long nanofibers from P3AT can be produced by electrospinning method, [24,51,52] while the shorter P3AT nanofibers are mostly formed via self-assembly in solution with good crystallinity owing to strong interactions along their longitudinal axis [53][54][55][56]. Other approaches, such as vapor-assisted imprinting [57], electrochemical synthesis [58,59] and solution casting method [60,61] using sacrificial templates have also been employed to prepare P3AT nanowires or nanotubes for diverse applications.…”

“…To date, significant progress has been achieved in the 1D engineering of conducting polymers for a wide variety of applications, such as batteries, supercapacitors, sensors, transistors, electrochromic displays, photovoltaics etc. [21][22][23][24]. Unfortunately, the development and performance investigation of 1D structured conducting polymers and their composites for thermoelectric applications are still limited so far, compared to the extensive research on the nanostructured inorganic thermoelectric semiconductors or semimetals [25][26][27][28][29][30][31].…”

Design Of A Bi-Functional α-Fe2O3/Zn2SiO4:Mn2+ By Layer-By-Layer Assembly Method

“…The prepared α-Fe 2 O 3 particles were coated with silica using a sol-gel method. In a typical procedure, about 40 mg of α-Fe 2 O 3 was dispersed in a water and ethanol mixture, after which 300 µL of NH 4 OH and 150 µL of tetraethyl orthosilicate (TEOS) were added. The samples were characterized by XRD and TEM.…”

“…Specifically, multi-functional inorganic particles with ceramic oxide are desirable in many applications in order to improve the stability of the encapsulated product [1][2][3]. Recently, we reported a core-shell structure with a non-toxic bi-functional magnetic ceramic phosphor which under silica coating and surface modification steps [4]. ZnO is an environmentally friendly ceramic phosphor that has been extensively studied as a fluorescent material for use in compound semiconductors due to its low price and non-toxicity [5].…”
