Paper Title:
Blue Fluorescent Liquid Crystal N-(4-methoxybenzylidene)-4-n-alkoxybenzenamine
  Abstract

Rod-like liquid crystals N-(4-methoxybenzylidene)-4-n-alkoxybenzenamine (MBnBA, n = 1, 2, 10) were synthesized and then were investigated by differential scanning calorimetry, polarizing optical microscopy, ultraviolet-visible spectrophotometry and fluorescence spectroscopy. Our results demonstrated that the dilute tetrahydrofuran solutions of each member in the family of MBnBA could give off blue fluorescence under the 325 nm excitation. The calculated electronic structures revealed that the fluorescence recorded at 469 nm (2.65 eV) was the result of π* → n transitions in the molecules of the synthesized liquid crystals MBnBA.
