ResumoAbstract The lighting and display solutions of the future are Organic Light Emitting Diodes (OLEDs). For the electron transportation, hole transportation and light emission, sequential layers of specially designed organic molecules and materials are used in OLEDs. The perfect blue‐emitters showing CIE (Commission Internationale de l′Eclairage) coordinates with a y‐component smaller than 0.1 are highly desired for OLED technology. Herein we report an efficient step economic protocol for the synthesis of a deep blue emitting fluorescent molecule named as “Ugi EML BLUE” (λ ems 443 nm; C.I.E. X=0.162, Y=0.012; HOMO/LUMO=‐5.94 eV/‐1.60 eV) suitable for the emissive layers (EML) of OLEDs and related applications.
