“…In our recent communication [32] we have reported on a new group of solution processable, electroluminescent organic compounds, namely tetraalkoxydinaphtho[2,3-a:2′,3′-h]phenazines, which extend the family of already reported linear and non-linear azaacenes, widely studied in organic electronics as promising semiconductors [33][34][35][36][37][38]. These derivatives can be obtained from indanthrone-an old alizarin-type insoluble dye-in a relatively simple, one-pot preparation involving the carbonyl group reduction with sodium dithionite followed by the substitution with solubility inducing groups under the phase transfer catalysis conditions [32].…”

An important application of organic semiconductors is to fabricate organic field-effect transistors (OFETs) which are essential building blocks for the next generation of organic circuits. In terms of molecular size or molecular weight, organic semiconductors can be divided into small-molecule and polymer semiconductors, and thus their corresponding OFETs can also be categorized into organic small molecule OFETs and polymer field-effect transistors (PFETs). On the basis of the main charge carriers transporting in OFET channels, organic semiconductors can be further divided into p-type, n-type, and ambipolar semiconducting materials. According to the characteristic of the organic semiconductors, the OFETs can be classified into two types: organic thin film transistors (OTFTs) and organic single crystal transistors. In any kind of OFET devices, organic semiconductor materials are the core; their properties determine the performance of the electronic devices. Therefore, the design and synthesis of high performance organic semiconductor materials are the basis and premise of the wide application of OFET devices. In the past few decades, great progress has been made in developing organic semiconductors. Besides organic semiconducting materials, there are many other factors influencing the performance of OFETs including device configuration, processing technique, and other devices physical factors, etc. In the following, a brief review of the development of p-type, n-type, ambipolar organic semiconductors and their field-effect properties is given. The history, mechanism, configuration, and fabrication methods of OFET devices and main performance influencing factors of OFETs are also introduced.

“…In addition to deposition location, alignment of polymer fibers and organic nanowires is desirable on many fronts and essential for equipment that utilizes and/or manipulates electromagnetic energy. Alignment of organic micro-or nano-fibers is beneficial for enhanced charge transport [231,232,263,264], production of polarized light emission [265,266], improved absorption and photovoltaic properties [123,267], and enhanced crystal properties [268]. Additional benefits of parallel fiber arrangement include directional cell growth [269] and guided cell differentiation [270] as well as the achievement of high-modulus, highstrength fibers, which can be used for heat-resistant and protective clothing [271,272].…”

Abstract:The fabrication of photonic and electronic structures and devices has directed the manufacturing industry for the last 50 years. Currently, the majority of small-scale photonic devices are created by traditional microfabrication techniques that create features by processes such as lithography and electron or ion beam direct writing. Microfabrication techniques are often expensive and slow. In contrast, the use of electrospinning (ES) in the fabrication of microand nano-scale devices for the manipulation of photons and electrons provides a relatively simple and economic viable alternative. ES involves the delivery of a polymer solution to a capillary held at a high voltage relative to the fiber deposition surface. Electrostatic force developed between the collection plate and the polymer promotes fiber deposition onto the collection plate. Issues with ES fabrication exist primarily due to an instability region that exists between the capillary and collection plate and is characterized by chaotic motion of the depositing polymer fiber. Material limitations to ES also exist; not all polymers of interest are amenable to the ES process due to process dependencies on molecular weight and chain entanglement or incompatibility with other polymers and overall process compatibility. Passive and active electronic and photonic fibers fabricated through the ES have great potential for use in light generation and collection in optical and electronic structures/ devices. ES produces fiber devices that can be combined with inorganic, metallic, biological, or organic materials for novel device design. Synergistic material selection and postprocessing techniques are also utilized for broad-ranging applications of organic nanofibers that span from biological to electronic, photovoltaic, or photonic. As the ability to electrospin optically and/or electronically active materials in a controlled manner continues to improve, the complexity and diversity of devices fabricated from this process can be expected to grow rapidly and provide an alternative to traditional resource-intensive fabrication techniques.
