Direct-Writing of Polymer Nanostructures:  Poly(thiophene) Nanowires on Semiconducting and Insulating Surfaces

“…Nanometer sized deposits can be achieved mainly by nanolithographic approaches. Next to surface probe microscopy techniques, for example dip-pen nanolithography (DPN), electrochemical DPN, electrostatic nanolithography, and electron beam lithography [236][237][238][239], nanolithography based on C-AFM has been extensively used for nanopatterning of monomer and precursor polymer films [240][241][242][243][244], in contrast with DPN and electrostatic nanolithography, in which monomer inks or electrolyte-saturated films are used [236,237,241]. C-AFM enables direct preparation of polymer films by electrochemical means on spin-cast monomers under ambient temperature and humidity conditions.…”

In the past 20 years the characterization of electroactive surfaces and electrode reactions by scanning probe techniques has advanced significantly, benefiting from instrumental and methodological developments in the field. Electrochemical and electrical analysis instruments are attractive tools for identifying regions of different electrochemical properties and chemical reactivity and contribute to the advancement of molecular electronics. Besides their function as a surface analytical device, they have proved to be unique tools for local synthesis of polymers, metal depots, clusters, etc. This review will focus primarily on progress made by use of scanning electrochemical microscopy (SECM), conductive AFM (C-AFM), electrochemical scanning tunneling microscopy (EC-STM), and surface potential measurements, for example Kelvin probe force microscopy (KFM), for multidimensional imaging of potential-dependent processes on metals and electrified surfaces modified with polymers and self assembled monolayers.

“…For one-dimensional nanostructures, CP nanowires and nanofibres have been prepared by a variety of methods, including dip-pen nanolithography (DPN) [113][114][115], electrospinning [116][117][118], template-assisted synthesis [119], soft template, vapour transport and deposition [120], and solution-phase self-assembly [121][122][123][124]. Controlling the dimensions (diameter or width d, length L) of nanowires is a key issue in the development of advanced materials.…”

Nanotechnology not only opens up the realm of nanoelectronics and nanophotonics, but also upgrades organic thin-film electronics and optoelectronics. In this review, we introduce polymer semiconductors and plastic electronics briefly, followed by various top-down and bottom-up nano approaches to organic electronics. Subsequently, we highlight the progress in polyfluorene-based nanoparticles and nanowires (nanofibres), their tunable optoelectronic properties as well as their applications in polymer light-emitting devices, solar cells, field-effect transistors, photodetectors, lasers, optical waveguides and others. Finally, an outlook is given with regard to four-element complex devices via organic nanotechnology and molecular manufacturing that will spread to areas such as organic mechatronics in the framework of robotic-directed science and technology.
