摘要：

Two novel furil-based small molecules FlBzPy and FlThPy were designed and synthesized with simple synthetic procedures for the first time for the LEC application. The optical, thermal, electronic, electroluminescent, and electrochemical properties were thoroughly analyzed. Both emitters exhibited excellent thermal and electroluminescent properties, which are required for a better LEC device. FlBzPy and FlThPy showed strong green emission at 511 and 514 nm, respectively. Additionally, they showed good power efficiency, quantum efficiency and luminance. In addition, the newly synthesized novel fluorophores showed CIE coordinates (0.23, 0.56) (FlBzPy) and (0.25, 0.53) (FlThPy) with better color purity.
