  2. 2. Synthesis of Conjugated Polymers and Small Molecules for Organic Light-Emitting Devices and Photodetectors

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Petri Henrik Murto; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; solution processing; conjugated polymers; fluorescence; near-infrared; light-emitting electrochemical cell; organic photodetector; organic light-emitting diode;

    Sammanfattning : Production cost and environmental impact are the two major concerns that are related to the conventional optoelectronic devices. It is desirable for the modern semiconductors that they are free of toxic/costly metals, they can be processed with low-cost solution-based methods, and their optical, electronic, and mechanical properties can be easily tuned depending on the target application.
