“…Some nanostructures involving nanotubes, nanorods, nanowires, nanoflowers, and nanopeapods have been produced by alumina template method [1–3]. It is a versatile cost-effective procedure employed to fabricate various nanostructures using polymer solution or melt [4, 5]. The wetting process of the alumina template to fabricate nanostructures deploys infiltration of solution into the nanochannels of the template through several methods such as immersion, spin-coating, and dip-coating methods [6–8].…”

In this study, low-bandgap polymer poly{[4,4-bis(2-ethylhexyl)-cyclopenta-(2,1-b;3,4-b′)dithiophen]-2,6-diyl-alt-(2,1,3-benzothiadiazole)−4,7-diyl} (PCPDTBT) nanostructures have been synthesized via a hard nanoporous alumina template of centrifugal process. Centrifuge has been used to infiltrate the PCPDTBT solution into the nanoporous alumina by varying the rotational speeds. The rotational speed of centrifuge is directly proportional to the infiltration force that penetrates into the nanochannels of the template. By varying the rotational speed of centrifuge, different types of PCPDTBT nanostructures are procured. Infiltration force created during the centrifugal process has been found a dominant factor in tuning the morphological, optical, and structural properties of PCPDTBT nanostructures. The field emission scanning electron microscopy (FESEM) images proved the formation of nanotubes and nanowires. The energy-dispersive X-ray spectroscope (EDX) analysis showed that the nanostructures were composed of PCPDTBT with complete dissolution of the template.

“…Among them, template assisted methods are commonly used for fabrication of 1D nanostructures such as nanowires, nanotubes, and nanodots [6,7]. Porous anodic aluminum oxide (AAO) membranes formed by anodization of aluminum in acidic electrolytes has become one of the most versatile template for nanofabrication [8][9][10]. A simple, two-step self-organized anodization does not require any sophisticated and expensive technology [11].…”

“…In addition, the pore density on the template can be controlled, and this determines the yield of nanowires synthesized (10 7 cm −2 to 10 10 cm −2 , typically). AAO templates are generally produced following a two‐step anodization process . Well‐aligned, hexagonally patterned cylindrical pores can be obtained.…”

to their wide range of tunable and potentially enhanced properties, as well as solution processing. Among the numerous conducting and semiconducting conjugated polymers processed into NWs and NTs and mentioned in this report, one can point out polythiophene (PT) and its derivatives, such as poly(3-metylthiophene) (P3MT), poly(3-butylthiophene) (P3BT), poly(3-hexylthiophene) (P3HT) andpoly(3,4-ethylene-dioxythiophene) (PEDOT), polypyrrole (PPy), polyaniline (PANi), polyphenylene-vinylene (PPV) andpoly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene](MEH-PPV), poly(9,9-dioctylfl uorene) (PFO), poly(9,9dioctylfluoreneco -benzothiadiazole) (F8BT), etc. Additionally, polymer nanocomposites, i.e. functional nanoparticles (NPs) inserted into a conjugated or notconjugated polymer matrix, are an exciting alternative to benefi t from the intrinsic properties of NPs and from the processability of polymers for 1D nanostructuring. Polymer nanocomposites have been processed into nanofi bers, for example by electrospinning and templating methods. Ultimately, optimal design with the juxtaposition of two or more materials in a 1D-like nanostructure is expected to promote improved properties, new behaviors, or to meet technological challenges. This is an emerging domain with very exciting perspectives.Although nanowires and nanotubes are the most common 1D-like morphologies, many others have been achieved with polymers, including nanofi bers, nanoribbons, nanorods, and nanosprings. The assembly and manipulation of such 1D building-blocks are still quite challenging due to their relative mechanical weakness because of their small diameter and very large aspect ratio. While in-solution methods are well developed for the assembly of nanostructures, the chemical stability of polymers in many commonly used liquids can also be a restraining factor.In the fi rst part of this review, the principles and recent developments of the main strategies used to synthesize polymeric 1D nanostructures are exposed. An emphasis is made on hardtemplating and electrospinning methods because structures with very high aspect ratios can be achieved, as are required for many photonic applications. In the second part, the various optical, optoelectronic, and photonic properties measured for these one-dimensional nanostructures are reviewed, including There is tremendous interest in one-dimensional nanostructures, since they permit enhanced properties as well as new paradigms for electronic, optical, optoelectronic, and photonic devices. Besides inorganic systems, nanowires (NWs) and nanotubes (NTs) containing an optically active polymer are now being intensively investigated. This article reviews recent developments in the various preparation methods and in the optically related properties of polymer-based NWs and NTs. The case of both conjugated polymers (CPs) and polymers containing photo-active species is described herein. The latest developments in synthesis methods allow the design of NWs and NTs with improved features or with more complex architect...
