Bisphenol A based pyrazoloquinoline dimers as dopants for electroluminescent applications

Abstract

A series of 1,3-methyl/phenyl (1,3-Me/Ph) bisphenol A based pyrazoloquinoline dimers (BAPQD) have been synthesized and characterized by spectroscopic methods. The obtained results demonstrate that recently synthesized dyes may be considered as promising materials for electroluminescent applications being used as dopants of PVK layers in OLED fabrication. The electroluminescent devices of the structure (ITO)/PVK:BAPQD-X/Ca/Al (X = 1–4) have been constructed and their current-voltage-luminescence characteristics are derived. In PVK host the 1,3-Me/Ph BAPQD derivatives emit light with different shades of blue color.
