State Ionic

Ionic liquids (ILs) are defined as organic salts with melting points below 100 °C. Such ionic compounds are typically formed using bulky cations and/or bulky anions in order to produce liquids or lower melting solids. ILs have been widely explored in several research areas including catalysis, remediation, solvents, separations, and many others. The utility of such compounds has also been recently broadened to include solid phase ionic materials. Thus, researchers have pushed the boundaries of ILs chemistry toward the solid state and have hypothesized that valuable properties of ILs can be preserved and fine-tuned to achieve comparable properties in the solid state. In addition, as with ILs, tunability of these solid-phase materials can be achieved through simple counterion metathesis reactions. These solid-state forms of ILs have been designated as a group of uniform materials based on organic salts (GUMBOS). In contrast to ILs, these materials have an expanded melting point range of 25 to 250 °C. In this chapter, we focus on recent developments and studies from the literature that provide for fine tuning and enhancing properties through transformation and recycling of diverse ionic compounds such as dyes, antibiotics, and others into solid state ionic materials of greater utility.

Morphology Of Films

The ionic materials were added to PEDOT/PSS solution as secondary dopants. The conductivity of PEDOT/PSS film improved with adding ionic materials. The film of PEDOT/PSS with 1% pyridinium p-toluene-sulfonate showed the conductivity of 23S/cm, which is increased about three orders than the film of origin PEDOT/PSS with 0.028S/cm. The surface morphology of films of PEDOT/PSS mixture is investigated by atomic force microscope. The AFM showed the increasing of grain size with the addition of pyridinium p-toluene-sulfonate.

Ionic Materials

This manuscript explores microwave-assisted reactions for the synthesis of new ionic materials involving the S-alkylation of thiophene. All isolatable products have been fully characterized by NMR and all product have been quantified through UV-vis spectroscopy. By means of a design technique, the experimental protocol (25 min, 200 W, 50 °C) has been optimized, which led us to better yields (96 %). In the absence of MW activation, the conventional thermal reaction at room temperature took longer (24 – 48 h) to obtain similar results.
