Luminescent Behavior of Liquid–Crystalline Gold(I) Complexes Bearing a Carbazole Moiety: Effects of Substituent Bulkiness

Organometallic materials that exhibit white luminescence in condensed phases are of considerable interest for lighting and display applications. Herein, new carbazole-based Au(I) complexes containing an isocyanide group a long pentyl chain were synthesized. The complex with unsubstituted carbazole moiety exhibited emission at room temperature as well nematic liquid crystalline behavior. Color tunability from to blue was achieved when bulkier substituents introduced the 3 6 positions moiety. Furthermore, all possessed phosphorescence lifetimes crystal state. proposed design framework provides opportunities practical applications using luminescent organometallic molecules.
