Ionic liquids (molten salts with melting points below 100 oC) have received considerable attention for their outstanding properties and wide scope of applications.A group of uniform materials based on organic salts (GUMBOS), i.e. organic salts with M.P between 25-250 oC, exhibit similar properties as ILs except these materials are solids rather than liquids. By changing the cation and anion, multifunctional GUMBOS such as fluorescent and conductive materials were synthesized and nanoparticles were prepared from these materials. Thermal properties were studied by use of thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC) studies showed that these materials are quite stable as GUMBOS-based materials. Photophysical and electrochemical properties were also examined. Based on these properties, thin film conductivity, photostability and photoluminescence experiments were performed using these unique materials to investigate their potential applications as organic light emitting diodes (OLEDs). Bandgap values were also determined by three different methods.
