POLY 339 |
| A series of annulated bis(azolium) salts of the general structure 1 have been synthesized and characterized as unique photoluminescent ionic liquid crystals. These compounds have many desirable features for ILC materials including tunable phase transition temperatures, modular components, excellent photoluminescent properties, and high thermal stabilities. The salts were stable in the melt under ambient conditions for extended periods of time, and thermal decomposition temperatures exceeded 300 °C. Emission wavelengths ranged from 350 to 550 nm, depending on the structure of the bis(azolium) salt and the corresponding countions, and quantum efficiencies in solution were determined to range from 30 to 90%.
