Abstract:
This work deals with the sensor application of polythiophenes, which belong to the group of the conducting polymers. The first part focuses on sensor application of poly(3,4-ethylenedioxythiophene) (PEDOT) for ion detection in aqueous electrolytes. The advanced electrochemical quartz crystal microbalance was used for investigating the electrochemical polymerisation and the redox cycling behaviour of the polymer films deposited on the liquid facing electrode of the quartz. This method is based on impedance analysis of a piezoelectric quartz crystal. The deposited polymer mass and surface roughn

Organic semiconductors combine the benefits of organic materials, i.e., low-cost production, mechanical flexibility, lightweight, and robustness, with the fundamental semiconductor properties light absorption, emission, and electrical conductivity. This class of material has several advantages over conventional inorganic semiconductors that have led, for instance, to the commercialization of organic light-emitting diodes which can nowadays be found in the displays of TVs and smartphones. Moreover, organic semiconductors will possibly lead to new electronic applications which rely on the unique

Intrinsically conducting polymers (ICPs) with high mechanical strength and electrical conductivity are attractive for several applications spanning the fields of energy, defense, and transportation. Electrochemically processed polythiophene (PTh) films are a class of ICPs that have been demonstrated recently to possess electrical conductivities as high as 1,300 S/cm and be stronger than common types of processed aluminum foils. While these results are promising, the electrical conductivity of PTh is still low compared to metals and the effects of important process conditions such as electrode

Metal-containing conducting polymers are a new and interesting class of materials that combine some of the redox properties of the conducting polymers and metal ions. In metal-containing conjugated polymers, there are several possible arrangements of the metal group relative to the backbone. This research focuses on the development of novel thiophene derivatives, with various side groups using different synthetic approaches and electrochemical polymerization. The resulting polymers could be excellent candidates for chemical sensors, solar cells, photoactive molecular devices and capacitors. Th

Different substituted thiophene and pyrrole monomers namely hexamethylene (bis-3-thiopheneacetamide) (HMTA), N-(4-(3-thienylmethylene)-oxycarbonylphenyl)maleimide (MBThi), 2,4,6-Tris-(4-pyrrol-1-yl-phenoxy)-[1,3,5]triazine (TriaPy), 2,4,6-Tris-(thiophen-3-ylmethoxy)-[1,3,5] triazine (TriaTh), and N-(2-(thiophen-3-yl)methylcarbonyloxyethyl) maleimide (NMT) were synthesized. The chemical structures of the monomers were characterized by Nuclear Magnetic Resonance (1H-NMR and 13C-NMR) and Fourier Transform Infrared (FTIR) Spectroscopies. Electrochemical behavior of the monomers in the presence and
