About this Research Topic
Organic optoelectronics is a new emerging field of outmost importance that has shown increasing interest, as more researchers and research centers around the globe are gradually involved in it. This discipline has sprouted from the recent developments in organic electronics. Currently, most of organic optoelectronics research revolves around the development and fabrication of thin films using novel materials. Typically, these films are employed as active layers in optoelectronic devices, i.e., OLEDs (organic light emitting or organic electroluminescent diodes), OSCs (organic solar cells), or OFETs (organic field effect transistors). Organic semiconductors pose as excellent candidates to promote specific applications in this named area of research. For example, conjugated polymers and molecular materials can play the role of donor or acceptor, or in some cases simultaneously the role of both, depending on their properties. These materials are in the form of copolymers, allowing the material to contain alternating donor and acceptor units. Due to their physical chemical properties, the copolymers can be easily applied as active layers, using well established technologies, and constitute part of single-component semiconductor OFET transistors. Similarly, various other candidate materials can be applied for a plethora of optoelectronic device components.
The current collection of articles aims to focus on the properties (and their characterization) of thin layered organic semiconductors, with the potential to be (or already being) applied in the field of organic optoelectronics.
A non-exclusive list of potential properties is as follows:
• Thermal properties (e.g., glass transition temperature, cold crystallization temperature, melting point, heat capacity, thermal conductivity, specific heat, latent heat, thermal stability and aging)
• Optical properties (e.g., optical band gap, refractive index, extinction coefficient, dielectric constants, optical absorption, transmission, luminescence)
• Mechanical properties (e.g., tensile strength, hardness, elasticity, young’s modulus, toughness, viscoelasticity, fatigue, creep)
• Physicochemical properties (e.g., molecular weight, wettability, solubility, partition coefficient, viscosity, corrosion, swelling)
• Surface and interfacial properties (e.g., surface charge/tension, z-potential, micro- and nanoscale topography)
• Electrical properties (e.g., conductivity, resistance, impedance, temperature coefficient of resistance, dielectric strength, thermoelectricity).
Evidently, the above-mentioned properties affect the performance, stability and operating time of numerous types of devices in the field of organic optoelectronics. In the submitted manuscripts, the main point of interest for the research should revolve around the characterization, identification, isolation, but also around modification and optimization of these properties, so that the functioning and operation of organic (opto)electronic devices will be positively and significantly impacted.
