Liquid Crystalline Coronene Derivatives with Extraordinary Fluorescence Properties
摘要:
Tempering of polystyrene films containing the novel liquid crystalline coronenebis(dicarboximide)s 2, which are formed by an easy route from perylene-3,4;9,10-tetracarboxylic dianhydride (1), leads to a shift of the emission within a few seconds. This could be used for dot-by-dot coloring and thus optical displays. The photoluminescence properties of 2 in the solid matrix are dependent on the nature of the aggregates formed.

The synthesis of liquid crystalline coronenediimides 9 and coronenemonoimide 10 is described in detail and the mesophases are investigated. A large intracolumnar charge carrier mobility of ca. 0.2 cm2 Vs−1 has been found for the discotic mesophase of the coronenemonoimide 10 using the pulse-radiolysis time-resolved microwave conductivity technique. The large mobility, together with the room temperature liquid crystallinity, make this compound an attractive candidate for applications as the electron transport layer in molecular electronic devices.
