π-Conjugated Organic Electroluminescent Molecules Based on Bipyridyl: Synthesis and Optical Properties

Abstract

A series of novel π-conjugated molecules based on bipyridyl were synthesized by Wittig-Horner reaction. Their structures were characterized by ¹H NMR, ¹³C NMR, IR, MS spectra and elemental analysis. All the compounds synthesized exhibit remarkable thermal stability as determined by thermal gravimetric analysis (TGA). The photoluminescence (PL) emission maximum peaks of materials prepared are in the range of 439～441 nm corresponding to blue light re-gion.

Key words: bipyridyl, blue light, thermal gravimetric unalysis, thermal stability, Wittig-Horner reaction
