Organic materials for holographic applications
… optical technology. This research explores organic materials for holographic applications in optical systems. A novel medium composed of azo dye molecules (methyl red sodium salt) and liquid crystals (PCB) was developed for holographic applications. A conformation change of azo dye molecules …

Field emission from organic materials
… begins by creating a field emitter out of organic conductors-a class of materials mostly neglected to date for this application. The organic emitter is made by copying a non-lithographic template. The process takes 5 minutes, occurs at room temperature and at atmospheric pressure, and does …

Electrocaloric and barocaloric effects in organic materials
Electrocaloric (EC) and barocaloric (BC) materials undergo reversible thermal changes in response to changes in applied electric field and pressure, respectively. These materials could potentially be exploited in novel solid-state cooling systems that may replace current vapour-compression systems, …

Organic materials with acenoid and iptycene structures
… UV-vis absorbance spectroscopy results of these materials are also discussed. It was demonstrated that the substitution of alkyl/alkoxy groups on the main chain not only provided better solubility in common organic solvents, but also subtly tuned the crystal structures and electrochemical …

Toward the Synthesis of Designed Metal-Organic Materials
Metal-Organic Materials (MOMs) are an emerging class of crystalline solids that offer the potential for utilitarian design, as one of the greatest scientific challenges is to design functional materials with foreordained properties and eventually synthesize custom designed compounds for projected …
