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.

多组分反应（MCR）辅助合成基于香豆素的深蓝色发射体，用于OLED及其相关应用

未来的照明和显示解决方案是有机发光二极管（OLED）。对于电子传输，空穴传输和发光，在OLED中使用了经过特殊设计的有机分子和材料的连续层。OLED技术非常需要能显示出CIE（国际照明委员会）坐标且其y分量小于0.1的完美蓝光发射器。本文中，我们报告了一种有效的步骤经济规程，用于合成名为“ Ugi EML BLUE”（_λems 443 nm； CIE X = 0.162，Y = 0.012； HOMO / LUMO = ‐5.94 eV / ‐1.60）的深蓝色发光荧光分子。 eV）适用于OLED的发射层（EML）和相关应用。
