Abstract
A new series of highly photoluminescent benzobis(imidazolium) salts with tunable electronic and physical properties is described. Systematic structural manipulations provided a set of materials that were not only fluorescent in the condensed state but also displayed tunable glass transition temperatures ranging from -0.3 to 113 degrees C. Upon heating, these robust materials flowed while maintaining their emissive properties. Further phase tuning was demonstrated through the synthesis of two thermotropic liquid-crystalline fluorescent benzobis(imidazolium) salts.
