Novel 4-(2,2-diphenyl-vinyl)-phenyl substituted pyrene derivatives as efficient emitters for organic light-emitting diodes

► PVPP and TPVPP show high solid-state quantum yields. ► PVPP and TPVPP exhibit high glass-transition temperatures of 127-150 °C. ► The amorphous films of PVPP and TPVPP are morphological stability. ► Multiple substitutions are beneficial to decrease the LUMO energy level. ► PVPP and TPVPP are promising host-emitters with high efficiency and stability.
